Managed to screw myself. Help please

Hi dudes. 85 Lebaron 2.2 tbi auto.

Had a voltage regulator wired in. It failed, and to get home I was going to ground out whatever wire made the alternator full-field, because I know it's good. Anyway, I grounded out the wrong one. Saw smoke, didn't catch it before the car died. Smells like I cooked the PM. Tugged on all the fusible links and they all seem okay.

Has anyone done this before? Looks like a PM issue?

Turning the key to run or start does nothing. Still have lights radio etc.

I may have a PM Kicking around from an 85 2.2 turbo. Will it work?

Power top non-functional as well.

I lied. Radio does not work.

Seems like everything on the ignition circuit.

[Big_P]

Windows do work though... Odd.

[shackwrrr]

Sounds like you killed a fusible link. Start tugging on them and find the stretchy one.

I was under the impression that all of the PM's are the same...at least all the "later" ones.

I would also check the biggest of the fusible links...heck i'd be persistent...it really has to be a main feed wire...

I don't think it's a fusible link. I tugged on all of them pretty hard (bazingaaaa) Pretty sure it's the PM. Hope I've got another one.

Okay. So it was a fusible link. Ha.

Is there a way to figure out what amperage it was so I can wire in a fuse? The wiring loom was cooked and I can't see what was on it.

There is a chart on Russ Knize's Minimopar site with the amperage rating of the fuse links by color.

I believe the ratings are listed in the FSMs too, just in case someone finds themselves out in the shop without computer access.

I've also read that the power modules will interchange between turbo and TBI cars, but I've never tried it.

I just recently replaced a fuse link on a Spirit R/T....just so you know if you decide to replace with another fuse link, the fusible link wire that NAPA sells are different colors than factory. I blew out an original orange fuse link and the correct amperage replacement was bright blue from NAPA.

I don't know for sure, but I would be surprised if the TBI and Turbo Power Modules are the same considering that the Turbo version had an additional injector driver over the TBI stuff.
