I am struggling with an electrical problem on my 1994 F250 IDI. Long story short, when I turn on the running lights, I can't turn them off without disconnecting the battery. After disconnecting the battery (main headlight switch off), I can reconnect the battery and no running lights until the headlight switch is turned on and the cycle repeats. I replaced the headlight switch and problem continues. NOW, when I remove the #4 engine compartment fuse (trailer running lights) the problem does not occur so I am suspecting running lights are backfeeding from the trailer circuitry.
I have several questions:
1)Checking power to the #4 fuse, I am getting 12v always on the right terminal. Can someone verify this is correct for me?
2)Are their areas in the wiring from fuse box to trailer receptacle that could be easily evaluated for the cause?
My schematic reading stinks and I am no electrical expert. Any help? Thanks!
