Question from an electrical novice. If the house batteries are dead or defective, do they prevent the shore power from working? We have a 50A circuit on our house and the breaker seems fine. Plugge...
How does the breaker seem fine? Did you turn it off then back on? Did you check voltage? You need 240 between L1 and L2. 120 between L1 and ground and L1 and neutral. 120 between L2 and ground and L2 and neutral. 0 volts between Neutral and Ground. Don't waste you time until you do this. Also turn your main breaker on and off in the RV. 12 volt will not effect the 120 system.
