Mystery

So, I had my 36 year old MSD ignition crap out. A hole corroded through the bottom, and the Jeep stalled. It restarted several times and I got it home. The tach was bouncing all over the place and it stalled again several times.

I ordered a new MSD. Installation was pretty straight forward, just hook the wires where the old ones were.

Now, I went to start it up and I have no power. No lights, no power anywhere. Battery shows 12.7 volts. I have power to the solenoid on the wheel well, and swapped it with my spare just to make sure. I have used three batteries, all of which checked out good.

Still no power anywhere.

1979 Cherokee 360 ci.

Any suggestions?

You have a bad fuseable link, look at the starter solenoid area.

I already swapped the solenoid with my spare. I guess I’ll replace the fuse able link off the negative battery cable.

They are off the positive side, should be a few of them there.

I could only see one in the 1979 service manual, so, I checked it out and saw that I had reattached it to the wrong post on the solenoid.

Mystery solved! Thanks!
