Power to AC's on Generator
I have a 2003 Bounder D/P with Onan generator. On 50amp shore power I can get both AC's to run but on the generator I only have the rear unit. The thermostat shows that I have them both turned on "Coo...

so i gotta check it while gen is running and i have the access panel open?
Your transfer switch should have two big relays. One is for shore power and the other is for the generator. Each relay should have three sets of contacts. Two of the contacts are hot and the third is a neutral. Both should look identical which the wires coming into the switch, shore and generator. If you feel up to it, with the coach plugged in AND the generator running if everything is working the incoming voltages to both relays should be identical but only one of the output side should be active.
When you're doing the checks on live circuits just be careful. Don't be touching or leaning against anything metal. As long as you're not grounded the possibility or getting shocked is reduced. An excellent tool to help make this easier is what I call a power sniffer. One Of These.
