How can you test the resistance of an ignition coil?
Testing the resistance values of the coils using the ohmmeter. If a high-voltage diode is built into an ignition coil to suppress sparks, it is not possible to measure the resistance of the secondary coil. Connect a voltmeter in series between the secondary winding of the ignition coil and a battery.
How is the ignition coil of a spark plug checked?
Ignition coils have two circuits that need to be checked: the primary and secondary ignition circuit. Connect the positive and negative leads of your multimeter to the positive and negative terminals of your ignition coil.
Where do you test the secondary winding on an ignition coil?
To test the coil’s secondary winding, attach the test probes to the outer 12-volt pole on the coil and the center pole (where the main wire goes to the distributor). The 12-volt pole is the spot where the power comes into your coil. It will be marked with a + sign, or it might only be indicated by a number.
What should my Briggs and Stratton ignition coil reading be?
Place the negative lead onto the metal body of the ignition coil – again ensuring it makes proper contact. Look for the reading on the multi-meter. A reading of 2.5-5.0 Kohms indicates the ignition coil is in working order.
How do you test a spark plug ignition coil?
If necessary, remove any plastic covers that may be covering the ignition coils. Step 3: Disconnect the wiring harness for the ignition coils. Remove them using your hand tools. Ignition coils are usually very simple to remove, often times only held in by one or two bolts. Step 4: Test the ignition coil’s primary ignition circuit.
How to test primary resistance of ignition coil?
To test the primary resistance on the coil, grab a multimeter and attach the positive probe to the positive terminal on the coil. Then, attach the negative probe to the negative terminal. Set the multimeter to 200 ohms in the resistance category and take the reading. Typically, the primary resistance should be somewhere between 0.4-2 ohms.
Do you need scanner to test cop ignition coils?
To test the COP ignition coils you do not need an automotive diagnostic scan tool (commonly known as a scanner or scan tool). You do need a few basic tools and these tools won’t break the bank.
How to test external ignition coils for motorcycle, ATV?
Ignition coils are easy to test, and don’t even require removing them from your motor. You just need a multimeter and a few minutes. Follow along with Evan, our Electrical Engineer, as he shows you how to test different types of powersports stators. Loading…
