It's me again I am learning how this forum works

If that's the case, it sounds like it would have to be a short after the ignition circuit.

Did you use the same gauge wire when you replaced it? Did you replace the whole wire or just the burnt section you found?

Sounds like it might have been a fusible link?

[Miro1]

Sorry I don't even know what is a fusible linkCould You please give me more details.

I have used smoller wire to be safe,but there is a short for shure the insutation starts melting and gets very hot.

I take it smaller wire = smaller gauge (bigger physical wire than factory).

You are going to have to trace that wire back. It is grounded somewhere. Not fun, but that's about all you can do.
