I have a 1967 John Deere 1020 Diesel. The lights were functioning fine when I decided to move a new light from the front fender to the rear. I figured it grounded during installation and blew a fuse because now none of the lights work. I talked with my local Deere parts guy. He sold me an AR28493 Circuit Breaker which come to find out was not bad. I can’t see any other fuses on this tractor. Ideas? Could it be the switch itself? Ive not had a chance yet to run a tested for voltage yet. Hopefully that will tell me. I was just hoping someone here would say, oh I had the same issue. Below is a pic of the wiring.
