1972 Safari wiring...help!

[scooterbobby]

OK, just started sorting out the little toaster i got...it's a 72 Safari.23'. all the lights work except one cuircit. looked and found blown fuse..easy! replaced fuse. hey! the sink lite, the middle light and the door light all worked! THEN...towed the trailer and ..no lights! fuse was blown. replaced it and immediately blown. OK, i'm a 20 year mechanic. so i have a direct short somewhere in my PINK wire (from the service book) cuircit. so, unplugged all i could from the harness(stove blower,sink lite,center lite,heater,and door lite) still blows fuse..SO..my question is , since this seems to be a shrt in the body cavity(mice,age,?) does anyone know where the wires are run from the back to the front? i know many of you have stripped the interior from these guys , so ya gotta know where they run the wires. around the bottom,across the top, where?
any ideas?
thanks in advance..

The wires for the 12v circuits run behind the interior walls. Though it's possible that the short could be somewhere along those runs, my experience has been that most shorts usually happen near the loads (i.e. lights and fans). Look for bare wire touching other metal or wires.

Good luck and tell us what you find.

Mike.first off,thanks for responding..
.i have all the loads unhooked from the cuircit..where in the walls? down both sides? where does the door light and center light feed from? left ore right or did they run the wires down the center? the hard thing is there is ! pink wire out of the fusebox...where does it split to go to the loads? if it all happens behind the panels...well that sucks. like i said when i got it the fuse was missing..plugged one it and things worked..moved trailer and fuses blow constantly now.. maybe i should put the trailer back in the old spot!
any help on where the wires are would help. i figured someone would have pulled the walls off one of these and could give me a clue..
thanks

Bobby,
First disassemble each light fixture, one at a time, and inspect the wiring going to each light make sure that no wires are bare, crimped, or pinched. You mentioned that the stove fan and furnace are on that circuit, too. If all of the lights check out, then check the wiring for them too looking for the same thing. If I was a betting man I'd bet your problem is near a light, fan or your furnace.
