Ignition coils are important parts of a car’s engine, and they can fail over time. If you’re having trouble with your car’s ignition, it’s important to check the ignition coil to see if it’s the cause.

Checking an ignition coil is a relatively simple process that can be done with an ohmmeter. An ohmmeter is a tool that measures electrical resistance. When you connect an ohmmeter to an ignition coil, it will measure the resistance between the primary and secondary windings of the coil. The resistance should be within a certain range, which will vary depending on the make and model of your car. If the resistance is too high or too low, it could indicate that the ignition coil is faulty.

To check an ignition coil with an ohmmeter, follow these steps:
1. Disconnect the negative battery terminal.
2. Remove the ignition coil from the engine.
3. Connect the ohmmeter to the primary windings of the coil.
4. Read the resistance on the ohmmeter.
5. Compare the resistance to the specifications for your car.
6. If the resistance is too high or too low, replace the ignition coil.

Determining Proper Ignition Coil Resistance

Ignition coils are crucial components in the ignition system, transforming low voltage electricity into high voltage to ignite the spark plugs. If the ignition coil fails, it can cause the engine to misfire or even stop running. Therefore, it’s essential to know how to check ignition coil resistance to ensure it’s functioning correctly.

Each type of ignition coil has specific resistance specifications, and deviation from these values indicates potential issues. Consulting the vehicle’s repair manual or examining the coil’s technical data sheet will provide the correct resistance measurements for your specific coil.

It’s important to note that resistance measurements can vary depending on the temperature of the coil. Therefore, it’s recommended to allow the coil to cool before performing the test and compare the readings with the manufacturer’s specifications at the same temperature.

How to Determine Proper Ignition Coil Resistance

1. Disconnect the ignition coil: Locate the ignition coil and disconnect the electrical connector. This step is crucial for safety, as working on an energized coil can result in electrical shock.

2. Set up the ohmmeter: Turn on the ohmmeter and set it to the lowest resistance scale. This will provide the most accurate readings.

3. Touch the probes to the terminals: Hold the ohmmeter’s probes firmly against the terminals on the ignition coil. One probe should be connected to the positive terminal, and the other to the negative terminal.

4. Read the resistance: Observe the ohmmeter’s display to determine the resistance value. Compare this value with the manufacturer’s specifications for your specific coil.

If the measured resistance falls within the specified range, the ignition coil is likely functioning correctly. However, if the resistance is significantly higher or lower than expected, it indicates a potential problem with the coil and further diagnosis is required.

Measuring Primary Resistance Using an Ohmmeter

An ohmmeter is a device used to measure the resistance of an electrical circuit. It can be used to test the ignition coil’s primary resistance, which should be within a specified range for the coil to function correctly. Here’s a detailed guide on how to check the primary resistance of an ignition coil using an ohmmeter:

  1. Gather the necessary tools: An ohmmeter, a spark plug wire, and a pair of pliers.
  2. Disconnect the spark plug wire from the ignition coil: Using the pliers, gently pull the spark plug wire from the coil terminal.
  3. Set the ohmmeter to the correct setting: Most ohmmeters have a dial or switch that allows you to select the resistance range. Set it to the lowest resistance range, typically 0-200 ohms.
  4. Connect the ohmmeter leads to the ignition coil terminals: Touch one lead of the ohmmeter to the positive terminal (+) of the ignition coil and the other lead to the negative terminal (-).
  5. Read the ohmmeter display: The ohmmeter display will show the resistance value in ohms. Record this value for comparison with the specified resistance range.
  6. Repeat the process for other ignition coils (if applicable): If you have multiple ignition coils, repeat steps 2-5 for each coil to check their primary resistance.

Note: The specified primary resistance range for ignition coils varies depending on the make and model of the vehicle. Refer to the vehicle’s service manual for the correct resistance values.

Symptom Possible Cause
Engine misfires or runs rough Faulty ignition coil with high or low primary resistance
Engine won’t start Ignition coil with open or extremely high primary resistance

Interpreting Primary Resistance Readings

The primary resistance reading of an ignition coil provides insight into the condition of its primary winding and the coil’s overall functionality. The reading should be within the specified range provided by the manufacturer. If the resistance falls outside this range, it could indicate issues with the coil.

Too Low Resistance

A primary resistance reading that is significantly below the specified range indicates a short circuit within the primary winding. This could be caused by a damaged insulating material or a short between the primary winding and the core. A shorted primary winding prevents the coil from generating the necessary magnetic field to induce voltage in the secondary winding, rendering it inoperable.

Too High Resistance

Conversely, a primary resistance reading that is significantly above the specified range suggests an open circuit within the primary winding. This could be caused by a broken wire or a damaged connection. When the primary winding is open, no current flows through the coil, which prevents it from generating any voltage in the secondary winding. As a result, the spark plug will not receive the necessary spark to ignite the air-fuel mixture.

Normal Resistance

A primary resistance reading that falls within the specified range indicates that the primary winding is in good condition. In this case, the coil should be able to generate the necessary magnetic field to induce voltage in the secondary winding and provide a spark to the spark plug.

Resistance Reading Interpretation
Below specified range Short circuit in primary winding
Above specified range Open circuit in primary winding
Within specified range Primary winding is in good condition

Checking Secondary Resistance

The secondary resistance of an ignition coil is typically in the range of 5,000 to 15,000 ohms. To measure the secondary resistance, follow these steps:

1. Disconnect the ignition coil from the spark plugs and distributor cap.

2. Set the ohmmeter to the highest resistance scale.

3. Touch one probe of the ohmmeter to the positive terminal of the ignition coil and the other probe to the negative terminal.

4. Read the resistance on the ohmmeter. The resistance should be within the specified range for the ignition coil.

Resistance Condition
Less than 5,000 ohms Ignition coil is shorted. Replace the ignition coil.
Greater than 15,000 ohms Ignition coil is open. Replace the ignition coil.
Within specified range Ignition coil is good.

Understanding Secondary Resistance Specifications

The secondary resistance of an ignition coil is a measure of the resistance encountered by the high-voltage current flowing through the secondary winding. This resistance is typically specified in kilo-ohms (kΩ) and varies depending on the specific ignition coil design and intended application. Generally, higher resistance values result in lower voltage output but increased spark energy, while lower resistance values produce higher voltage output with reduced spark energy.

The specified secondary resistance range for a given ignition coil is typically provided by the manufacturer and should be used as a reference when testing with an ohmmeter. If the measured secondary resistance falls outside of the specified range, it may indicate a problem with the coil that requires further investigation.

Resistance Range (kΩ) Spark Energy
0.5 – 1.0 Very low
1.0 – 2.0 Low
2.0 – 3.0 Medium
3.0 – 4.0 High
4.0 – 5.0 Very high

It’s important to note that the specified resistance range may vary between different types of ignition coils and should be referenced from the manufacturer’s specifications for the specific coil being tested.

Identifying Open or Shorted Secondary Windings

To detect an open or shorted secondary winding, you’ll need to measure the resistance across the secondary terminals of the ignition coil. Follow these steps:

1. Set Your Ohmmeter to a High Resistance Scale

Typically, the resistance of a secondary winding ranges from 5,000 to 50,000 ohms. Choose a scale that offers enough range to accommodate these values.

2. Ground the Ohmmeter’s Negative Lead

Connect the negative lead of your ohmmeter to a good ground point on the vehicle’s engine or chassis.

3. Insert the Positive Lead into the Coil Tower

Push the positive lead of your ohmmeter into the center of the coil tower, where the high-tension spark plug wire connects.

4. Read the Resistance Value

Observe the reading on the ohmmeter’s display. The resistance should be within the specified range for the ignition coil. If it reads “OL,” it indicates an open circuit, while a reading close to zero suggests a short circuit.

5. Inspect the Spark Plug Wires

If you suspect an open or shorted secondary winding, check the spark plug wires thoroughly. Look for signs of damage, wear, or loose connections.

6. Compare Measured Resistance to Ignition Coil Specifications

Ignition Coil Type Secondary Resistance Range (Ohms)
Distributor Ignition Coil 5,000 – 15,000
Coil-on-Plug Ignition Coil 7,000 – 25,000
Waste Spark Ignition Coil 10,000 – 35,000
Electronic Ignition Coil 12,000 – 40,000
High-Performance Ignition Coil 15,000 – 50,000

Refer to this table to compare your measured resistance values to the specified ranges for different ignition coil types. Deviations from the expected ranges may indicate a faulty ignition coil.

Testing for Continuity

Step 1: Set the Ohmmeter to the Continuity Setting. Locate the continuity setting on your ohmmeter, typically denoted by a musical note or ohm symbol with an arrow through it. Set the dial to this setting.

Step 2: Connect the Ohmmeter to the Ignition Coil Terminals. Touch one probe of the ohmmeter to the “positive” terminal of the ignition coil and the other probe to the “negative” terminal.

Step 3: Observe the Ohmmeter Reading. If the ohmmeter displays a low resistance reading (typically below 1 ohm), it indicates continuity, meaning the electrical circuit between the terminals is complete.

Step 4: Reverse the Ohmmeter Leads. Switch the probes of the ohmmeter (positive to negative, and vice versa) and repeat Steps 2 and 3. The ohmmeter should still display a low resistance reading.

Step 5: Test the Individual Coils. If your ignition coil has multiple coils, test each coil individually by disconnecting them from the spark plugs and repeating Steps 2-4 for each coil.

Step 6: Check for Intermittent Continuity. Gently wiggle or tap the ignition coil while observing the ohmmeter reading. If the reading fluctuates or breaks intermittently, it may indicate a loose connection or damaged insulation.

Step 7: Troubleshooting Intermittent Continuity. If you suspect intermittent continuity, visually inspect the ignition coil for any loose connections or damage. If none is found, use a multimeter to check the voltage supply to the coil. A low voltage supply can cause intermittent continuity issues.

Table: Ohmmeter Readings for Ignition Coil Continuity Testing

Reading Interpretation
Low resistance (below 1 ohm) Continuity is present
High resistance (above 1 ohm) Continuity is not present
Intermittent reading Possible loose connection or damaged insulation

Troubleshooting Ignition Coil Failure

Checking Primary Resistance

Remove the ignition coil from the engine. Disconnect the wires from the coil’s terminals. Connect an ohmmeter to the primary terminals of the coil, which are usually marked with a “+” and a “-“. The normal resistance range for a primary winding is typically between 0.4 and 2 ohms.

Checking Secondary Resistance

Connect the ohmmeter to the secondary terminals of the coil, which are usually located on the top of the coil. The normal resistance range for a secondary winding is typically between 5,000 and 15,000 ohms.

Checking Spark Plug Wires

Inspect the spark plug wires for damage or cracks. Replace any damaged wires.

Checking Distributor Cap and Rotor

Remove the distributor cap and inspect it for cracks or carbon buildup. Clean or replace the cap and rotor if necessary.

Turn the ignition switch to the “on” position and check for power at the ignition coil. If there is no power, the problem may be with the ignition switch.

Checking Battery and Charging System

Make sure that the battery is fully charged and that the charging system is functioning properly. A weak battery or a malfunctioning charging system can cause ignition problems.

Additional Tests

* Spark Test: Disconnect a spark plug wire from a spark plug and hold it close to the engine block. Have someone crank the engine and look for a spark. If there is no spark, the problem may be with the ignition coil, spark plug wire, or distributor.
* Coil Peak Voltage Test: Use a coil peak voltage tester to measure the voltage output of the ignition coil. The peak voltage should be at least 20,000 volts.

Symptom Possible Cause
Engine misfires or stalls – Faulty ignition coil
– Damaged spark plug wires
– Worn distributor cap or rotor
– Faulty ignition module
– Weak battery or charging system

Additional Diagnostics for Ignition Coil Malfunctions

If the ohmmeter tests indicate a malfunctioning ignition coil, further diagnostics can help pinpoint the specific issue:

Visual Inspection

Examine the ignition coil for any visible damage, such as cracks, burns, or loose connections. Also, check the wiring harness for any signs of wear or damage.

Spark Test

To perform a spark test, remove the spark plug wire from the ignition coil and hold it close to the engine block while cranking the engine. If a strong spark is present, the ignition coil is likely functioning properly. However, a weak or absent spark may indicate a problem with the ignition coil.

Dwell Test

A dwell test measures the amount of time the ignition coil spends charging. To perform this test, connect a dwell meter to the ignition coil and crank the engine. The dwell time should fall within the manufacturer’s specifications. If the dwell time is too long or too short, it may indicate a problem with the ignition coil.

Substitution Test

If other diagnostic tests are inconclusive, a substitution test can be performed. Borrow a known-good ignition coil and install it on the vehicle. If the engine starts and runs smoothly, the original ignition coil is likely faulty.

Engine Performance Monitoring

Monitor the engine’s performance while driving. If the engine hesitates or misfires under acceleration, it may indicate a problem with the ignition coil. Also, look for any unusual noises or vibrations coming from the engine.

Scan Tool Diagnostics

Some vehicles have on-board diagnostic systems that can detect ignition coil malfunctions. Use a scan tool to retrieve any stored trouble codes that may indicate a problem with the ignition coil.

Ignition Module Test

If the ignition coil is part of an ignition module, test the ignition module as well. The ignition module may be faulty even if the ignition coil checks out okay.

Distributor Cap and Rotor Inspection

If the vehicle has a distributor, inspect the distributor cap and rotor for any cracks, burning, or corrosion. A faulty distributor cap or rotor can prevent the ignition coil from firing properly.

Fuel Pressure Test

Although not directly related to the ignition coil, a low fuel pressure can cause engine misfires that may mimic ignition coil malfunctions. Perform a fuel pressure test to rule out this possibility.

Next, use the jack to raise the vehicle. Be sure to place the jack in a sturdy location under the vehicle. Once the vehicle is raised, remove the lug nuts and pull the flat tire straight toward you. The tire should come off the rim easily. If it doesn’t, you may need to use a tire iron to pry it off. Once the tire is off, you can replace it with a spare tire. Be sure to tighten the lug nuts securely, and then lower the vehicle.

Lubricating the Bead

Applying a lubricant to the bead of the tire can significantly ease the process of removing it from the rim. This lubricant acts as a barrier between the rubber and metal, reducing friction and allowing the tire to slide off more easily. It can also help prevent damage to the bead or rim during the removal process.

There are several different types of lubricants that can be used for this purpose, including silicone spray, dish soap, and even vegetable oil. Apply a generous amount of lubricant to the bead of the tire, using a brush or your fingers to distribute it evenly. Allow the lubricant to soak in for a few minutes before attempting to remove the tire.

Here is a table summarizing the steps involved in lubricating the bead:

Step Description
1 Gather your materials: lubricant, brush or sponge, and tire iron.
2 Clean the bead area of the tire and rim to remove any dirt or debris.

    Electrical problems in your vehicle can be a real pain, especially when they’re caused by a parasitic draw. A parasitic draw is when your car’s battery is being drained by something even when the car is turned off. This can be caused by a number of things, such as a faulty alternator, a bad battery, or a short circuit. If you’re experiencing electrical problems in your vehicle, it’s important to test for a parasitic draw so you can find and fix the problem.

    There are a few different ways to test for a parasitic draw. One way is to use a multimeter. To do this, you’ll need to disconnect the negative battery terminal from your car’s battery. Then, connect the multimeter’s positive lead to the negative battery terminal and the multimeter’s negative lead to a ground. If the multimeter reads anything other than 0, then you have a parasitic draw. Another way to test for a parasitic draw is to use a clamp-on ammeter. To do this, you’ll need to clamp the ammeter around the negative battery cable. If the ammeter reads anything other than 0, then you have a parasitic draw.

    Once you’ve confirmed that you have a parasitic draw, you’ll need to find the source of the problem. To do this, you’ll need to start by removing fuses one at a time until the parasitic draw goes away. Once you’ve found the fuse that’s causing the problem, you’ll need to determine which circuit that fuse is responsible for. You can do this by referring to your vehicle’s owner’s manual. Once you know which circuit is causing the problem, you can start to troubleshoot the problem and find the source of the parasitic draw.

    The Basics of Parasitic Draw

    Parasitic draw is a condition where an electrical component or system continues to draw power from the battery even when the vehicle is turned off. This can lead to a drained battery and, in some cases, can even cause the vehicle to not start. Parasitic draw can be caused by a variety of factors, including:

    Electrical accessories: Electrical accessories, such as lights, radios, and power outlets, can continue to draw power from the battery even when they are turned off. This is because these accessories are often connected to the battery through a constant power source, which allows them to receive power even when the ignition is off.

    Electrical faults: Electrical faults, such as short circuits and faulty wiring, can also cause parasitic draw. Short circuits occur when two wires come into contact with each other, allowing electricity to flow through them uncontrolled. Faulty wiring can also cause parasitic draw, as it can allow electricity to leak from wires.

    Aftermarket electrical devices: Aftermarket electrical devices, such as remote starters and security systems, can also cause parasitic draw. These devices are often connected to the battery through a constant power source, which allows them to receive power even when the ignition is off. If these devices are not installed properly, they can draw power from the battery and lead to a drained battery.

    4. Systematic Testing

    This part of the test involves systematically checking each fuse location for a parasitic draw. Here’s a detailed guide:

    Step Procedure
    a. Insert the jumper wire into the fuse slot for the first circuit.
    b. Observe the multimeter reading. If the reading drops below 0.05 amps, that circuit may have a parasitic draw.
    c. Remove the jumper wire and insert it into the next fuse slot.
    d. Repeat steps b and c for each fuse location until a significant parasitic draw is identified.

    Isolate Circuit Suspects with Fuse Pull Method

    With the systematic fuse pull method, you methodically disconnect potential sources of parasitic draw by removing fuses one at a time. Here’s how it works:

    1. Gather Tools: You’ll need a multimeter, fuses of the correct amperage, and a fuse puller.
    2. Prepare Multimeter: Set the multimeter to DC milliamp (mA) mode. Connect the red lead to the positive terminal and the black lead to the negative terminal.
    3. Disconnect Negative Battery Terminal: Remove the negative battery terminal to prevent any electrical shocks.
    4. Connect Multimeter to Battery: Connect the multimeter leads to the negative battery terminal and a good ground on the chassis.
    5. Test Current Draw: Turn off all lights and accessories and wait for the parasitic draw to stabilize (usually around 30 minutes). Record the current draw displayed on the multimeter.
    6. Pull Fuses Individually: With the multimeter still connected, start pulling fuses one at a time, beginning with non-essential circuits.
    7. Monitor Current Draw: As you pull each fuse, observe the current draw on the multimeter. If the current draw drops significantly, you have likely isolated the circuit responsible for the parasitic draw.
    8. Identify Suspect Circuit: Once you’ve identified the circuit, refer to the fuse box diagram to determine the components or modules connected to that circuit.
    9. Inspect Suspect Circuit: Physically inspect the suspect circuit for damaged or faulty components, loose connections, or any other issues that may be causing the parasitic draw.
    10. Confirm Diagnosis: Reinsert the pulled fuse and check the current draw again. If the current draw rises, your diagnosis is confirmed.

    30 to 40 0.8

    Identifying Ground Faults and Short Circuits

    A ground fault occurs when the electrical current escapes from a wire and flows through an unintended path, such as the ground or a metal frame. This can be caused by damaged insulation, loose connections, or faulty wiring. Ground faults can be dangerous, as they can cause electrical shocks and fires.

    A short circuit occurs when the electrical current takes a shortcut through a low-resistance path, such as a wire or a metal object. This can cause the circuit to overload and trip the breaker or fuse. Short circuits can also be dangerous, as they can cause overheating and fires.

    There are a few ways to test for ground faults and short circuits. One way is to use a multimeter to measure the resistance between the electrical wire and the ground. If the resistance is low, it indicates a ground fault. Another way to test for ground faults is to use a ground fault circuit interrupter (GFCI). A GFCI is a device that detects ground faults and trips the circuit to prevent electrical shocks.

    To test for short circuits, you can use a multimeter to measure the voltage and current in the circuit. If the voltage is low and the current is high, it indicates a short circuit. You can also use a continuity tester to check for short circuits. A continuity tester is a device that checks for complete circuits. If there is a short circuit, the continuity tester will beep.

    Troubleshooting Ground Faults and Short Circuits

    If you find a ground fault or short circuit, it is important to fix it as soon as possible. Ground faults and short circuits can be dangerous, and they can also damage your electrical system. To fix a ground fault, you may need to replace the damaged wire or insulation. To fix a short circuit, you may need to replace the damaged wire or fuse.
