[Ozz]

My hard- mount 50 amp PD shut my system down in our 3400RL when I plugged in here in Tonopah, P-1 it says, P-1, correlates to E-1 as the previous code event.
Reverse polarity.
Checked the camp pedestal power supply, A-OK there.
So I shut all breakers off. Reset breaker at pole, cleared code.
One by one turned on power to individual circuits, happy happy happy until the entertainment center breaker turned on... Uh oh. Click click, P-1 it reads on the remote display. Ok we are getting somewhere now. I unplugged everything on the circuit, tried breaker... Uh oh. No joy. I pull the fireplace.. Think it is on that circuit, wanted to check it's wiring while I have some momentum, no joy with a breaker flip after reset.
So now I get to check j-box under desk slide, pull all outlets and check wires there.
Sucks to be me...
