Hi, New to forum!

I just picked up a pop up camper. It was rough but I cleaned it up pretty good.

My question is this- When I plug the camper into the house current all the electrical stuff works. When I try to switch over to battery nothing works. The battery is a fully charged marine battery.
Also- the potable water- Once the tank if filled how does the water get to the sink? Is there a pump I should be looking for?

BTW- Why is there a cooler that looks like a fridge in the camper? I thought it was a fridge.

When you say that nothing works what exactly do you mean? The 120 volts outlets will not work off the battery.

You should have a converter that will convert 120 volts into 12 volts and power the lights, water pump, furnace fan if you have these. Some converters have a switch that you have to change from 120 to 12 volts to get the lights and appliances to work off the battery. Also your converter may have a polarity fuse that could be blown.

Your battery may have a self resetting circuit breaker near the battery. Check it and make sure it is not defective.

You will also have a switch that shuts off the roof lights when the gallery is down. Other PUPs have the same switch by the bunkend. This switch might not be activated or is defective. Also there is a connector that is on the outside of one of the roof supports. Check it and make sure it is not loose. HOWEVER, if the lights work while you are plugged but not when you are on battery then this is not the cause.

Regarding the water system, you may have a 12 volt water pump that is activated when a facet is open and the pressure drops. You should have a pump switch and a fuse that you need to check. Other PUPs have a manual pump.

I'm not sure why you say you have a cooler versus a fridge. It may be a three way fridge (12 and 120 volts and propane) check on the outside and you will find doors that allow you to get to the controls. These fridges do not have a compressor and so they cool very slow and there is no sound like a house fridge.

Hope this helps.

This does help. I will check the things you mentioned.

It was definately not a fridge. I took it out and it weighs about 10lbs. No wires or connectors.
