Re: Only Lights That Turn On Are The Headlights!
Find that fuse and measure the voltage between the fuse terminal and the metal end of the fuse it's connected to on both sides with the light circuit powered up. If you see voltage you've found a bad connection at the fuse terminal. I'd also measure across the fuse itself since they can look fine but still be open at the end.
It's common for those 40 year old fuse terminal to get a layer of rust on them that can create some interesting gremlins.
