I've been having some ignition problems and before jumping on the Opti wagon and spending $200 for something that might not be the problem I want to check my coil. I have a Crane Cams PS91 coil and heard you could check them with an ohmmeter. Can anyone chime in with some info? Thanks.

 

This will test continuity and for excess resistance.

 

My coil only has 2 terminals though, not 4. 2 metal prongs that the plug connects to and then the high power output.

 

You don't have a stock type coil?

 

Nevermind, I found the specs on Crane's website.

Primary Resistance .43 ohms
Secondary Resistance 3.0 kohms

Is there any other way to test a coil?
