Camper Power: 110v vs 12v

[cj7zrcool]

Op, rather than spend $150-$200 on a battery, check your converter. If it's working and you are hooked up to 110v, then you don't need the battery other than in situations where 110 goes out. FYI, your camper thermostat is more than likely 12v so even if you are plugged into power, you won't get your AC on if the converter is not working.

The converter is what allows your lights to work off either "12v battery" or 110 with the converter from 110v - 12v. Your lights are actually wired for 12v power only.

Mine quit working a couple of years ago and I looked into getting a new one until I discovered the (2) 40amp fuses in the side of it, and one of them was blown. Replaced the fuse and it's been working every since.

This. My trailer does not have a battery and the lights are 12v. I replaced my converter few years ago because the cooling fan quit working. Make sure you check for fuses. They will be the auto blade type fuses.

Camper circuits generally require a battery to complete the circuit even if the inverter is working and giving 12v. Unplug from 120, hook up a good battery and see what works. If lights work, plug it back in and see what still works and check voltage at the battery to see if inverter is working.

This is what I wasn't sure of.

Now some on here say I don't need a battery and some do.

I'll put one in and check fuses on inverter.

Thanks fellers.

My slides wont work without a battery in place. Lights may or may not i've never tried, but they will work while plugged in with a dead battery in place. Check your large fuses just downstream of the battery as well, I chased an issue for a bit caused by a blown fuse. Mine now has resettable fuses in place.
