House batteries - Jrahn56 - 06-23-2025

I returned to my coach after being absent for 2 1/2 months on a medical emergency and found I had no power from my house batteries. Normally the lights above the microwave that indicate water level, holding tanks, and temperature were off, and I had no 12 volt compressor. I went out and checked the house batteries with a battery tester and all checked okay. I checked the inverter and it seems normal. Does anyone have a suggestion on what's the problem?

Thank you,

I’m guessing a fuse or a bad relay. Look for the 12 V fuse panel. On 316 it’s in the rear corner of the coach next to the main 220v breaker box. Do you hear a click when you activate the 12V main switch?

There are only 2 things that seems not to be functioning is the digital read out above the microwave and the lift for the bed. I have all of my 12 volt lighting. The 12 volt master switch is functioning correctly. I don't know which fuse controls that digital control panel and which fuse controls the bed.

Thanks,

I would just check each fuse there on the panel with a test light. It might be the same circuit powers both .

Thank you. I have the circuit board out now checking it with a ohms meter.

Thanks again.

don’t. Forget the 12V fuses in the passenger kick well, and in the hidden fuse block close by the inverter on driver side. I say hidden because Newell covered it with a carpeted box.

Richard, I don't know where you are talking about. My inverter is under my bed and the lift does not have power to it also.

Oops, my bad. No two Newells are alike. As Forest said, a box of chocolates.

The box Richard is referring to is about midway back on drivers side on 316. See upper left in this pic.
