Solid State Ignition Modules

Postby Pops506th » February 8th, 2018, 11:43 pm

Howdy all,

This is my first post here. I just picked up a 151A1 a couple of weeks ago and it came with a bunch of spare parts. Among those are two different types of solid state ignition. It appears that one type uses a special rotor and the other type uses the standard rotor but requires a change to the cam. What can you guys tell me as far as reliability of each and any other issues that I may run into.

Thanks

Welcome to the G, POP, share some pics of your jeep, the second pic is the Swiss module(latest and greatest) third pic is Prestolite model, both will work with no problem, the Swiss module is said to hold up better.

The Prestolite modules had a problem with the potting material degrading and melting out of them and then the electronic components would short out. As long as the potting materiel is good and solid and not gooey it would be fine. As was said, the Swiss controls units are known for holding up well but the Prestolites that don't degrade do just as well. One thing to mention is that the Prestolite is a magnetic pick up type and the gap on the pick up needs to be adjusted with a BRASS feeler gauge. The Swiss is an optical sensor and has no adjustment.

I went ahead and installed the Swiss setup.

I did run into an issue however. The coil that was installed had long mounting screws because the mounts on the coil were tall. Because of this, the ground wire for the module was too short. I removed the coil and found this setup underneath it. Anyone know what this is?

I had to unsolder the hot wire from the capacitor to remove it. I had a new coil and capacitor in the spare parts I got with the Mutt, so I installed them instead of this coil setup

do you have a multimeter? Might just be a resistor for that specific coil.

That is the early version of the coil which had the resistor attached to the bottom of it. They have not been available for many, many years. If that coil was still working then definitely hang on to it, it does have to be used with the resistor.

It was working just fine when I pulled it out. I only removed the points and coil to convert to the solid state because I hate screwing with points.

I did get some extra distributors with the vehicle, so I'll refurbish one of them with the points and re-install this setup in that one.

This is a good time to revisit the fact that good, working original coils are in short supply. DO NOT discard it! If you do, tell us where your garbage can is.

ANY NOS ignition parts are getting to be in short supply so don't throw out anything if it is still operable! The replacements are for the most part all Chinese and are total garbage!!

Yep. I'm hanging on to everything that is still working.

When did the Chinese stuff start hitting the market? I'm pretty sure none of the parts that I got with the vehicle were purchased after 1997 or so.

How can you tell the difference?

Probably about ten years ago, starting with the coils. Then on to the ignition modules. The coils are the chrome ones so if yours are all the dull looking ones you are good to go.
