Just not enough confusion on this thread yet.
A self resetting circuit breaker under the front of my camper. 3 Red wires. Maybe 1 feed and 2 loads?
Maybe for the circuit from the 7 pin plug to the TV?
Maybe for the Z AMP solar input tap?
I have not followed the wiring so I do not know for sure.
Just to stir the pot a bit more, 3 shots of places where wiring just lays on top of frame members:
I wonder how many miles it would take for the insulation to chafe through and cause a short circuit?
Note the blue wire in pix 2 and 3? That's for the trailer electric brake circuit.
That's a recall waiting to happen.
My solution? A few feet of poly hose from Lowe's as a protective cover.
Y'all might want to check your rig out when you have time.
Oh, one last interesting find. The negative side of the battery (white wire) is grounded to the frame by only one wire attached by only one screw. No redundant connection. If that goes, the whole 12 volt system - including exterior lights and trailer brakes - loose power.
10 minutes and 3 feet of #10 wire will fix it.
