My battery power switch keeps tripping, little green light going out. I depress it once and hear a click, then again and it lights back up and stays on for a while without issue.
I read some posts about looking for a relay but didn’t see anything obvious behind the WFCO panel. Unfortunately I’m single sided deaf so I can’t use hearing to find the location of the click. Sounds like it’s in my last good ear……
Does anyone know where this relay might be on a 2022 Caravel 19cb? Any other things to look at?
Thanks Steve I’ll check the battery voltage tomorrow when it’s not -9000 outside. Right now everything is working so I’m afraid to touch anything…..it seems the light just kinda flickers, no real pattern or rhyme or reason. Then sometimes it’ll turn off completely, yet through all of this all of my lights, the furnace, etc. continue to work.
Will the 12v stuff work when on shore power even if the battery power switch is “off”? I’m wondering if it’s a loose connection or something related to the little green annoying circle of light….
All the 12vshould work on shore power no matter if the relay has the batteries connected or not. Find your Intellitec Battery Guard relay and check for secure connections.

Okay I’ve looked under the drawer to the right of the circuitry panel, I’ve looked behind the cover of the panel, nothing looks like the relay pics I’ve seen. My next guess is under the cabinets of the small sink to the left of the panel. I have to figure out how to access the area as it’s boxed in. I feel like the decorative panel off the floor will pull off but I don’t want to just yank on it
I'm betting your relay is attached to the back of the converter. See the attached picture, what's behind that panel? If there is no other access you'll have to take off the converter cover, then the screws on the front edge of the converter to pull it out. If that's the only access, the factory will have (most likely) left enough slack in the battery and shore power cables to pull it out.

See attached pic. Is that your closet on top of the converter? If so and there is no access hatch at the bottom of the closet, I'm more convinced you'll have to pull the converter to find the battery relay.
Steve
Hey Steve, you were correct, the relay is behind the converter. The floor of the closet has some screws that can be removed to allow access. I pulled the closet floor and snugged up all of the nuts on the relay. The larger one didn't really move any, but two of the smaller ones snugged up a bit. I haven't had any issues with the battery power light flickering since, so crossing fingers that was it.
Congratulations!
Now, for your next task... there are two possible configurations/modes of the Battery Guard Relay: Chassis mode and Coach mode. The relay will disconnect your batteries at differing voltages depending on the configuration. In Chassis mode it will disconnect your batteries if the voltage dips below 12.1v. The Coach mode disconnects at voltages below 10.5v. If you had a Class B van and you were protecting the engine starting battery you'd want it in Chassis mode.
When we first had our trailer (Dec '21) I had no idea there were two modes. We had lead acid batteries (I wasn't about to pay $4000 for lithiums from the dealer). We were dry camping in a vineyard with the weather below freezing. We were able to run the furnace for only a few hours before the voltage drop caused the Battery Guard to disconnect power! I was upset that the trailer couldn't make it overnight without running out of power. (We now have lithium batteries)
In reading manuals and posts on the forum the answer came from forum user OrangeCrush who mentioned the two modes of the relay.
See the attached info, you'll most likely need two people to do the configuration test but I suggest you find out what mode your Battery Guard is in.
thanks Steve! I'll check it out when I'm back home. For now, with the furnace working (had a furnace issue first night out as well), and my power working I'm afraid to touch anything until I'm in my driveway
I just returned from a weekend out in the cold, 6.8° F was the lowest at night. Saturday morning in noticed the Dometic CCC2 thermostat that used to show "FURN" was showing "A9UA". It was hard not to fiddle with it but the furnace was working so I kept my fingers in my pockets.
When I got home I did a thermostat reset and I'm back to "FURN"
