What ignition coil should I use?
The 3.0-ohm coil should be used on PerTronix Ignitors installed on four- and six-cylinder engines while 1.5-ohm coils should be used for eight-cylinder applications. These coils can be used on virtually any inductive (non-capacitive discharge) ignition system.
How can you tell if you have a bad coil?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.

What is the difference between a points coil and an electronic ignition coil?
In an electronic system, you still have a distributor, but the points have been replaced with a pickup coil, and there’s an electronic ignition control module. In this system, coils sit directly on top of the spark plugs (there are no spark plug wires), and the system is completely electronic.
How can you tell if a plug coil is bad?

- Worsening Gas Mileage.
- Diminished Power.
- Sudden Backfires.
