There is an excellent thread on this list covering the testing of coils, so there is no need for guess work. I got a lot out of that thread! This site rocks!!

Exactly my thoughts. The coil is less likely to go out than the electronic ignition though. :mrgreen:


The electronic module is actually very dependable unlike the coils which are a very common problem. I see very few module problems and LOT of bad coils. Older Prestolite modules have a problem with the potting material getting soft and then shorting out components on the board but the Swiss controls units are very dependable.

Well ya learn something every day! Thanks, Rick! :D

Re: Distributor - test for electronic ignition?

Is there a test procedure for the electronic ignitions? Swiss or Prestolite?
I found procedures for testing coils and capacitors but the electronic ignition is a little more involved as I've been told.

If it is in the vehicle then with the cap off and ignition on put a 24 volt test light on the negative side of the coil and crank it over. Light should flash on and off for every cylinder. I am not sure if this will work with a LED test light or not, I have never tried it but it should. When doing this test it is a good idea to run a jumper wire from the center terminal of the coil to ground so that the coil does not arc internally.

Husker, converting to points is easy, all you need is the point plate and the parts to go on it. Elmer, Prestolite electronic ignition is solid state ignition yes, but the Prestolite units have a lot of problems with the potting material going bad on the circuit boards. They have not made them for many years. The Swiss controls units are much better.

Check places like Frontline and Red River, other than that you are looking at old distributors. I probably have one somewhere but I am not going to be able to look for it for a while. M38, M38A1 will be the same so there is another place to look. Same distributor if I remember correctly. You will have to ask the M38 guys about that.
