Didn't think about turned my off th battery disconnect. Lol. I assumed they were to the chassis, but someone be else said elsewhere that one of theirs in their days went to the hous battery. Basically same unit.
Can I use other 12 volt line to splice onto like a light? What I am wanting to do is figure out a way to power a cpap when not on electricity. The battery bank is in the front part of the Motorhome and the bed is in the back. There are no 12 volt plugs anywhere else in the coach. I though it getting a pure sine wave inverter and installing it, but the. I would have to run an extensions n cord through the Motorhome because of trying to mount the inverter near the batteries. And then Finding a good pace to mount it is another thing.
