Missing Shore Power

[CdA]

Hi, new member here from lovely Kingston, TN. Our Luna Rover suddenly decided that it wasn’t getting shore power. I checked the cord, the Luna receptacle and the 30 Amp breaker (just making sure it hadn’t tripped). I will be rechecking all of the above again. Any other suggestions will be very much appreciated!

Do you have multi meter and know how to use it? May need to check some components and find the failure.

Thx for reaching out! Yes and yes!

Any chance your battery connections are loose? Our trailer uses the battery to complete the circuit even when it's on shore power and I find I have to really tighten the clamps to get power.

Always a possibility, thank you! I will check!

Especially if you have an inverter or inverter charger. They need battery power to operate and start the battery charger.

I checked. All good. I get power at the 30 amp breaker but nothing else and the 12 v circuit works. I guess the breaker could be bad...

Which breaker? In the rig or the source for the receptacle. In the RV there can also be a connection problem where the breaker plugs into the panel bus. When was the last time the wiring connections have been checked for tightness. Panel, transfer switch, inverters, power cord, etc. All the crewed in place connections.

That’s the breaker directly connected to shore power. No, I have not done the checks you mentioned since it’s only a 2022 that hasn’t seen that much use….but I will. Thx
