C5 Fusible Link
Seeing if I can get a correct response here.
My c5 fusible link from the alternator to the starter is going all wonky. If I jiggle it I get a overcharge message and my dash goes out but I am not over charging. It's the original starter and wiring which looks old and corroded. From alt to bat 14.6 even though dash states 18. Its the only wire if I jiggle that triggers it. Ignition switch (new) no issue with wires, alternator (new) no issue with wires.
I seen from searches that I can and cant replace it. Can I cut the old one out and replace it (crimp and solder)? Some searches said I cant that I have to buy a new harness.
If I can is it just a 10G fusible link wire to replace it with? Done this a many of many of times of fourth Gen Fbody's from headers burning them.

You should be able to replace the fusible link at the starter if you can find another fusible link. That is what I would try to do.
Yes the exhaust (headers) can cause problems with them.
You are lucky you found the problem, I am sure it was not easy to track down..

Wasn't easy. Thought it was one thing and then another and then another. So 6 months later and many things replaced thought problem was resolved. A test jiggle jiggle and replicates issue.

Its a new starter. Was replaced to see if the solenoid was causing the issue. Issue went away until the wire got jiggle again over a speed hump last week. Connection feels tight until to jiggle the wire.
