Ok guys don't laugh. When I first got this truck (51 Chevy 3100), I hooked up a 12 volt battery on a 6 volt system. Headlights and turn signals that were working stopped.
Since I have gotten the correct battery, replaced headlight bulbs, 2 fuses inside engine compartment and turn signal fuse inside cab. Headlights and turn signals still aren't working.
Parking lights, dash lights and interior work fine so I don't think it's wiring. Plus they were working before I did the dumb battery thing.
What am I missing?
