Electrical problem...no radio, running lights, interior lights...

[Lotsa_Faith]

Happened a couple weeks ago, just got around to trying to fix it. Goin down the road, all the sudden radio cuts off, interior lights cut off. No running lights, fog lights, but brakelights, blinkers, and headlights still work. I've checked all the fuses in the fusebox, all good. What could be the problem? Its also a M1009 converted to 12 volt, so that doesnt help alot either...

it sounds like a fuse problem since i beleive all those are on the same curcuit. if it isnt the fuse i would look at your grounds in the cab. good luck

Check all the wires going to the starter, one of them might have burned off.
