Testing an Ignition Coil on the Car
If you're getting no spark at your spark plugs, you might have a bad ignition coil. The ignition coil sends the spark to the distributor, which then sends the sparks out to the spark plugs.

Bench Testing Your Ignition Coil
Your ignition coil can be the culprit in many automotive troubleshooting situations. You will need to test your coil to see if its bad.

This type of coil testing can tell you if your coil is on the way to being bad even before it is obvious.
