Lost 12V power. Breaker Location

2015 Palazzo 35.1

I lost 12VDC power to a fuse panel; drivers side front basement.
The circuit board has a #4 (?) wire/terminal J1 labeled, "CHASSIS BATTERY IN FROM BREAKER."

Does anyone know where the breaker is to restore power to this panel?

I would imagine that there is in 'inline' fuse breaker, not a 120v circuit breaker as you may be thinking. Following the wire back to the chassis battery may be the best bet, but look first in the battery bay itself, as there are several 'bus fuse's mounted on the wall that can sometimes trip, with a little 'yellow flag' protruding. Push it back in.

I agree with you TurnerFam.

I found the two 100 A push-button breakers but they are fine.

I'm trying to figure out if a relay in the inverter bay might be the problem.
The relay is open; one terminal is 12V and the other terminal is 0V.

It's the best picture I could get with the wiring harness covering the relay.

Big picture of where the relay is located in the inverter bay.

I've checked all the fuses outside of the fusebox. Hoping a small ampere fuse is blown that prevents the coil picking up to the heavy #4 wire.

Thanks,
Don

You are correct sir. I could not see the 'yellow flag.' But, today I got on my knees and examined the battery compartment. I got a different perspective and reset the yellow flag and the power was restored!
