So, a toy hauler rolls in with a dead battery from the night before, as well as AC power issues.
DC battery was down to 6+ volts, really dead. The truck barely got it charged and there is some speculation as to the new Fords giving full charge voltage back to the trailer (mine doesn't).
Air conditioner was not working all night either. Pretty much tripped the breaker once asleep, only to wake up to a too warm coach.
The pedestal breaker kept tripping. But it only seemed to be tripping when the DC stuff was working, the converter, which wasn't all the time.
A little checking found a 35 amp fuse in the converter appeared to be overheated, but not popped. Changed the fuse, converter works, turn on air, breaker trips.
Best we could figure out was that one of the two fuses was loose in the socket causing an intermittent converter operation.
Batteries get low, converter running full output, AC compressor kicks in, trailer shakes, fuses wiggles and the converter kicks in and out.
This was a 30 amp service trailer.
So, with the air conditioner running at maybe 15 amps and the converter kicking in on high and drawing maybe 12+ amps, and going in and out due to vibration, the main AC breaker was tripping at the pedestal.
The converter was pulled, the sockets tightened up, fuses replaced and everything was fine for the rest of the weekend.
