12 Volt System Not functioning

I need a little help. My inverter monitor panel reports 12.1 volts so I am pretty good with battery level. I have checked all of the 12v fuses in the panel and all appear to be good. Checked battery disconnect and it is on. With all of this I have no 12v lights, vent fans, etc. Have I missed something, is there something else I need to check or reset? t get my 12 volt system back?

12.1 volts is a dead battery.

Should be between 12.7 and 12.9 volts or so, and jump up to over 13 when the coach is plugged into shore power.

Yes, I agree, 12.1 is a dead battery!

Ok. Thanks for the information. I will recharge the batteries again and see what happens.

Batteries have been charged. Still no 12v DC to coach. Anyone with any ideas. Tried talking with Redwood customer service and they basically left me on my own.

Does anything function in the coach while plugged into shore power? If that's not practical, how about plugged into the tow vehicle while the engine is running? How sure are you of the health of your batteries and connections? I understand you have no 12 volt anything that works, correct? Slides, refrigerator, range hood, docking lights?

You say you have an inverter, not a converter? If you do not have a residential refrigerator than you probably have a converter. I would suspect the converter if you are getting nothing from shore power. The converter runs on shore power check all circuit breakers. Have you tried, as suggested, the hydraulic system or slides?

I would start at the batteries themselves and work back. Be sure to look at the ground. Without a good ground, the 12 volt system is dead. While checking the ground look at the connection at the "Buz Bar". Also check the fuses on the inverter itself. You can get to them by dropping down your service wall (at least on the 36RL) they're on the side of the inverter. I would guess your issue will be found very close to the batteries

Being a 2014 if you have an invertor which runs the residential fridge. You will still have a convertor which should be in a closet by the door which converts the shore power to 12 volt. Check all of the fuses in this unit. You either have the main fuse feeding it bad or there is a possibility which I have had before that your convertor is toast. If you have or someone you know can check the voltage with a meter you can see if you have 120 volts coming in and no 12 volt going out
