Something is drawing too much current and tripping the factory circuit breaker. Your description of the wiring is a clue
Step #1 Get someone who is familiar with the cars and electrical portion of them.
Step 2 Start with new harnesses straighten out the ignition system. Lot's of choices there.
Might be a good idea to park it and keep the battery disconnected in the mean time
I've had my hand all over these car but had no idea there is was a factory circuit breaker. Where is this located. Why would it not blow the fuse?
My hope was that once these harnesses are replaced along with the ignition cured that the light issue will be a thing of the past.
The dimmer switch is new Barry and I checked it and surprisingly not melted like many I have seen.
The headlight switch connection has evidence of a few hot trips. It is not destroyed but disformed a bit in a couple areas.
