Ok, so I have been slowly replacing all the chewed up wires in mt 62 GMC 3/4 ton, (cab was so full of rat poops that it was up to the dash) I'm pretty close to having it all going just need to finish fuel gauge and brake lights, blinkers, and dome.
The wire for the dome light was pretty much gone so I ran new wires up to it but was not sure what wire went to what side and figured I got a 50/50 shot. hooked it all up and hit the switch, but nothing. I then flipped the bulb around and it lit up but with the dimmer in the off position. I figured I had the wires backwards, so I swapped them around, and flipped the bulb again, and same thing happened just this time the bulb had to be put in correctly to light up (with switch still in off position).
I left it that way for 2-3 days with the switch in the on position (with the light off). This morning when I went out to the truck for round 2 the battery was was almost all the way dead, it just cranked over 1 time then nothin'.
I have it on the trickle charger now and will start again this evening.
No combo of swapping things around got the dimmer to work correctly it's only on in the off position and when I roll through the dimmer nothing happens.
The bulb is a LED DC-12 error free 3 SMD 42mm dome trunk cargo area light. seemed to fit well and lit nice and bright just in the wrong position.
Would this be a problem at the switch itself? I know the PO methed up the wiring quite a bit before the rats got to it all. (some of the intact wiring was really weird with alot of "extras" like 3 horns and 4 antennas 2 blinker switches doubles of most gauges and brake lights that ran separate from the original tail lights that appeared to be from a trailer) The rest of the switch functions properly with all other lights working (besides blinker and brake)
I would not be surprised it the wiring at the switch was backwards, but it does not appear to wired by the PO as his stuff was pretty obvious. Although the switch appears to have stock wiring he may have just done a better job that time.
