Wow,

Fabulous reply. Thank you. I do have a working high beam, it is only right-low and both fogs that are inop. The fuse doesnt show power at all. I will test again.
I just purchased some copper fuses with plans to replace the lot. I will clean the contacts in the box after disconnecting the battery.

With out looking closer, it isnt clear where the terminals and other references mentioned are, but once poking around it may make more sense. I hope the connections are labeled as you mention. This would make it easy. Your description is reasonable.

First step, I'll clean the fuse box terminals and replace ALL the fuses.

Who is "the bird" that you mentioned I should get fuses from? I can only assume this is a slang name that means nothing to me at the moment.

I'd love to get a copy of a wire diagram at some point if possible.

Thanks again for the help. This gets me closer than I was this morning.
