I have a 1970 Cuda and the wire coming from the bulk head to the fuseable link (blue wire) that connects to the solenoid is getting real hot only when I turn on the headlights or just running lights on with the Ignition in the off position. It does not get hot with lights off, and car running. I have traced this wire and it goes to the ignition switch. I have just recently changed the ignition switch, so that may be ruled out as problem. (not really these days) Then I disconnected the amp gauge and connected the 2 wires together to see if that would help, but it didn't. I have checked all the grounds to the headlights and they seem to be doing the job. If I would leave the lights on for any length of time it would melt down.
What can be causing this?
