Thanks for the welcome! I have been reading everything here that I can here, a lot of knowledge on this site that’s why I finally joined. Can you point me I. The right direction for where to find info on 12v power on my camper?

Thanks for the welcome! I have been reading here a couple weeks deciding it was time to join. Can you point me in the right direction for where to talk about 12v power?

The 12 VDC power comes from 2 places

1. Out on the A-Frame of the trailer tongue, behind the two propane tanks there should be a 12 Volt battery. There might be two batteries if the prior owner added a second one. This battery is used to provide braking power to an emergency breakaway switch/cable that hooks to the truck. If the cable gets pulled, the switch activates and applies the trailer brakes in the event the trailer disconnects from the truck. This is a federal safety requirement when towing down the road.

That same battery also provides power to the inside of the camper to run the lights, water pump, furnace, free idge control system, radio,tv attend booster and the LP detector

2. There is a power converter in the camper, or was when Sunline made it, that when you plug into shore power, 120 VAC, the power converter system creates 12 VDC to both charge the battery on the trailer A-frame and power all the 12 VDC items in the camper.

The power converter system is a power center so to speak. There are 12 VDC fuses and 120 VAC circuit breakers to protect the branch electrical circuits in the camper. There is also a power converter system inside the power center with fans for cooling the system that transforms the 120 VAC to 12 VDC.

To find the power center/power converter look down low near the floor for a metal or plastic panel about 12” x 12” approximately. Not knowing the year of your T-320SR camper we not sure of the make or model of the power center. Or if a prior owner changed it


Looking at the T-320SR floor plan, the power center might be mounted in the side of the bottom bunk in the left rear corner. Or it might be in the bottom of the cabinet to your left as you walk in the rear entry door. I’m not sure exactly where yours is, the above is suggestions based on similar floor plans. If you strike out and can’t find it, then start at the outside of the camper where the shore power cord enters the camper. The converter most times is very close to the place where the cable enters the camper. In your case, the bottom side of the left rear bunk makes the best guess

Hope this helps. A little more than you asked for but good info to know in case you didn't know.

2001 it’s a centurion 4500 it came with the owners manual it has so much stuff in it. You are right it’s in the cabinet right as I walk in on the left there outside the bathroom

[GregS]

So I have power to everything when I plugged in today but nothing works off the battery any trouble shooting ideas or a switch to go to 12v?

The first thing would be to check if you have a fully charged battery. If it is good then go to your converter and check the green 30 amp fuses. The 30 amp fuse is a safeguard in case you connect the battery wrong. There could also be an inline fuse between the battery and converter. I have never had to deal with that fuse but otlhers on this site have had to.
