My 65 Sport Fury had everything working. I took out the head light switch to scuff up the contact points and lube the moving parts just a bit. The dash lights would not reach thier brightest setting and was very sensitive when you turned it down or up. It was hard to get the dash lights to come on at all, let alone as bright as they should be. Went to put it back in and only get high beam and low beam head lights. No dash, courtesy, tail or park lights. Just head lights. Brake lights and turn signals are fine. I tried 3 different head light switches (two of which are new) and still the same. I only get head lights. Wiring diagram shows no relay in that part of the system. I do not get juice to some of the fuses in the fuse box unless I use a jumper wire at the head light switch plug. UPDATE: I fixed it. It was a bad connection in the fuse block.

 

OK, I fixed it. It was a loose wire in the fuse block.
