63 C10 only about half of fuses box has power .I have tail lights,blinkers front and back. I just pulled this ruck home so still trying to figure out what is what and what was cobbled together. Key on I only have about 3 fuses hot pulled fuses to make sure they are good contact and looks like no wires are butchered up or spliced. So my ? is reading the schematic from FAQ forum the hot comes in through the light switch and then to the fuse box.I lose power at the firewall and no power at rad. support.I'm thinking the light switch is the culprit any ideas ?

I lost power to my headlight circuit when the power wire on the back of that circuit had corroded. I had to crimp on a new connecter and everything worked again. I also thought it was the headlight switch, so I replaced it, but that still wasn't the issue. I found the corroded wire after the switch replacement

Ok changed out the floor dimmer switch and got my headlights new and the fuse panel is working as it should.So went over to the heater have no fan notice on the wire schematic that it doesn't show the fan switch wiring.
