This is making me scratch my head. I noticed about a month ago that when I turn on the headlights, the alt light comes on on my gage cluster. Thought I might have a short - can't find one, and the generator output remains constant in all switch positions. Then I thought - gee, I noticed this problem when I changed out the burned out bulb in the alt light. After, closely examining the switch, I think the alt light is wired hot so it comes on just like the headlights. I cannot find a diagram that will show me which wires go where on the switch. Anyone have a suggestion or link?
