View Full Version : Help! No power to Ignition Coil

Hello all,

I discovered why my car quit me the other day while on a test drive...I'm not getting any power from the ignition terminal in the fuse panel to power my coil for some reason. I have a Pertronix Electronic ignition and a Pertronix 12V coil. The coil instructions say that the coil needs a full 12V with no ballast resistor. Therefore, I ran a wire from the ignition blade in the fuse panel direct to the coil. It was working fine until the other day.

I don't see any fuses blown or anything obviously wrong otherwise. I decided to post this here in troubleshooting instead of electrical in hopes someone may have a quick answer on what to check...

Any help appreciated!!

Check connections, and also for breaks in the wire. Use a test light on the ignition switch terminal. You also might want to run a hot from your ignition switch directly to the coil to see if the switch has a short. If there are no blown fuses, either the wire is bad to the fuse box, or the switch could have given up the ghost, IMO.

Ok....Thanks for the tips.

I am getting 12V to the coil now. But, still no fire. I tried my old Delco coil and tried a New Accel super stock coil...still no fire. So I suspect the Pertronix electronic ignition module.

I have my old breaker points re-installed at the moment. There is only one lead wire coming from the dist. and it goes to positive on the coil right? and the neg. on the coil just goes to ground right? It's been several years since I messed around with points so I don't remember exactly how it all went together.

Of all problems, I hate working on electrical problems the most.

Any help appreciated...

Wire from the dist. goes to the negative side of the coil. Ignition wire goes to the positive. This will work for testing purposes, but if you plan to leave it this way you'll need to hookup the original resistor wire or a ballast resistor to the positive side of the coil.

Thanks 12run,

Yes, the points are just for testing purposes so that I can pinpoint the source of the problem.
