Can anyone lead me to a diagram of what terminal does what on a headlight switch for a 65? (I think 64-72 were the same?). I want to understand this switch so I can see if my old one is really dead, or if I am just wasting my money on a new one.

I could also use some guidance on different testing procedures for the switch. I did see a decent post by cjoe on 2-16-2007 that gave some advice, but It would be helpful to know what terminal is doing what.

If there is no resource known, maybe I will post my own testing results, although my electrical skills/understanding is definitely "apprentice"!

can anyone recommend a good book or website that guides newbies through automobile electrical testing and troubleshooting?


Thanks, Jerry.
