melting wires, round two.
okay so last summer I ran into Charge System Fault messages and the such, turned out to be some burnt up wires from the header on the pass. side.
mainly the wire running from the positive battery terminal to the starter post to the alternator post.
so I ran into some electrical issues the other day and after replacing the alternator and that not fixing it and then taking a closer look (like i should have from the start) - the wires by the pass. header appear burnt again. :argh: .. off comes the header .. again.
any solutions for a wire wrap that won't burn under the extreme heats of Florida sun and high temp exhausts? I mean I want to be able to haul my girl across the alley (Alligator Alley for those not in FL) in 5th at 2500 without burning up wires.
thoughts?

WOW !! Thats EASY. Just GOOGLE thermal heat wrap and tons of things come up. Heres what I use.

I also order some nylon wool insulation and glue it inside that wrap. That adds even more protection. Ive made the following shields with that stuff.
- AC Compressor shield
- Starter shield
- Clutch line shield
- Wiring shields.
- AC low pressure line shields.

I don't think it is the heat inside the car that is causing your problem. Here in Bakersfield, it can get to 110 in the summer and we have computer systems in metal cabinets that sit in the direct sunlight with no cooling fans and I never had wires change color. I think you still have a short somewhere that is getting your wiring too hot and that is discoloring your wiring. Have you changed any fuses? If you have, double check the amp ratings on them and make sure they are correct before you wiring shorts out and burns up more than the wires.
