The truck has developed an intermittant short in the lighting circuit :au: which encompassed the dash and courtesy lighting (20A Fused). A fuse was blown while driving time 10 minutes, with lights on at a constant 75mph on smooth wet road with a moderate rain shower. I suspected that the trailor harness splicing or connector had become saturated, and inspected the wiring and found no splicing so I assumed it to be a factory install then cleaned harness connector with tric. dried and tied in a less vulnerable position to road spray. The connector was in good shape physically. The next day was dry and roads dry as well and the fuse blew at about the same amount of driving time.
What I would like to know? Is there any harness disconnects for front to back or left to right that would allow me to isolate each of the looms and ring out the wires to rectify this resistive short since it is probably not a direct short I'm suspecting either a chaffed wire or a possible wire strand shorted which is not enough to blow the fuse immediate but instead generates a slow build of heat which eventually causes the fail. :au:
Darn me, I posted this to the wrong thread. Should have been under tech. I think. And I don't know how to move it now. Sorry Mod.
