I have a 90 APV. The headlight switch gets hot and will shut my headlights off on me. The parking lights stay on. Ive replace the headlight switch and the dimmer switch but they still get hot. If I use my brights, it gets hot even faster. Ive checked all grounds and all power wires for shorts but cant find anything. The switch just gets hot where the yellow wire is. But that yellow wire runs to the dimmer switch. Someone please help me!
