How do you test coils?

[PWilliams84]

someone please tell me how you use a voltage meter to test whether or not the coils are good..i know this is how you check, just dont have any experience doing it

pull off the wires for the coil you want to test and connect your multimeter leads to each terminal, then check the resistance. what engine do you have?

2 ways.

1st way: Remove each coil. You must test the primary and secondary resistance. Use a hanes manual for this. It tells you how to test for both, as well as what ohm values you should be within.

2nd way: Leave the coils on the car, and pull one plug wire off at a time (from the coil). Start the car with one plug wire off at a time. If you hear a sparking/zapping noise, then the coil is good (you should hear it for both cylinders on a coil).

If you decide to use this method please be sure to record this on the highest quality camera you have.
