I plugged in to 110 tonight to turn the fridge on and have lights to start packing. My microwave numbers are lit and my CO detector is lit but nothing else works. No lights work, the fridge "check" indicator comes on.12volt lights do not come on either. Thoughts??Where do I start? We leave Wednesday for a week long trip, go figure, so not enough time to get it into the shop. Thanks in advance for your help!

Start with a volt meter. I suspect you have an open GFCI, either in the house or in your RV.

Start with the battery voltage. Then voltage on the 12v fuses.If the battery is dead and not charging you converter could be shot. For an immediate fix you could get a 10+ amp battery charger for the trip.

110 goes to a breaker box. If you have 50 amp service, maybe one side is not working. Or you do not have power from the 110 service to the 12 volt converter and the battery is disconnected.

Is the battery disconnect (salesman) switch in the disconnect position? In some units the converter is on the battery side of the disconnect switch, so with it turned off there isn't any 12V power for general house loads.Usually the CO detector is wired to the 12V system, so there apparently is 12V power somewhere. Often it's not disconnected via the usual disconnect.

your problem is NO 12vpossibly dead battery, bad connection, blown fuse, disconnect switchyour lights are 12v, the fridge and almost everything else uses 12v either for control circuit aka the fridge, or for main power aka lights water pump heater etc..

If the fridge indicator light is on the disconnect switch is not disconnected. If it was there would be no indicator light on.

So, I checked the plug (outlet), good power to plug (outlet). Battery disconnect is on. I checked all fuses, none are blown. I checked the battery cables, the positive cable was very slightly loose. I tightened it and added water to the battery. It was a little low but not bad. The converter is new as of this summer, the battery is 2 years old.

Most of the lights, the fridge, and the pump now come on...yay!!! I have 2 lights that still do not come on.

Thanks everyone!!!! I am making progress.

Sounds like the loose cable was the Tribble in the quadrotriticale. (ST Reference).

The lights not working....

On my RV I have several lights that have multiple switches.. ONE on the lamp itself and one (or 2) Elsewhere. These inluce the overhead light in the bath and half bath. Bedroom 2 in the main room and one over the steps. BOTH the lamp's on-board switch and the "Remote" must be on for light to light.

2nd. though Bob may be your friend BOB (Burned Out Bulb) is not.
