I think you remove one of the spark plug wires from the coil and hold it far apart from the coil. Have someone turn the key so the car is turning over. Bring the spark plug wire closer to the coil and if there is spark the coil is good. Note: if you hold to close you will get a very good jolt of spark if the coil is good, that is why you start far away and work your way closer.

How do you test the coil on 1994 Toyota Corolla?
remove the distributor cap and clamp a test light to ground. hold the point of the test light about 1/2" from the coil output electrode. have someone crank the engine and look to see if sparks jump across to the point on the testlight. if they do the coil is ok. if they dont clamp the testligt to the + terminal of the coil and put the point on the - side. again, have somone crank the engine, if the light flashes the signal is good. replace the coil.
Why would a test light placed on the distributor side of the coil flicker when the engine is cranked?
It is normal. In order for you to create a spark, the coil has to open and close.
How do you test a coil pack on 2002 trailblazer?
Pull each coil plug off one at a time while the engine is running... The coil pack that is bad will NOT have a difference in engine noise, but the ones that are good you will hear a slight decrease in engine noise when you unplug the coil and then plug it back up again... Hope this helps everyone!
How do you test ingition coils on a 1999 s80 Volvo?
If the reason you want to check the coils is because of a check engine misfire code swap the coil with a coil from another cylinder, clear the codes, drive if the check engine light comes back on see if the code follows the coil you moved. If so replace the coil.

How do you test a small engine ignition coil on a 22 hp kohler while the coil is not installed?
You can't test a coil off the unit the only way to test the coil is disable the kill circuit if it fires it mean u have other problems such as a safety switch problem like seat switch or neutral safety switch. The above answer is completely false. You use an ohm meter and test to manufacturers specs for the ohm of your specific coil, typically in the 8,000 ohm range +/- 2,000 ohms. Save
