Is that in the coach battery compartment?

If so it maybe a sensor wire for an inverter (if equipped) or a power supply for something else.

Yes these are the house batteries, my xantrex does not work so it could part of that.

The first thing I would do is trace the wire and see where it goes. Do you know if it is supposed to be on the positive or negative? Hooked up wrong it could get real expensive real quick........

The weird thing is that based on the length of the wire and the size of the terminal it does not look like it is meant to hook directly to a battery. Is there something else in the compartment that is within reach of the wire and the right size post for the terminal? What about empty screw holes where something like a breaker or switch used to be installed but is gone now? As to tracing the wire, first I would just visually try to see where a wire the same size and color jumps out of the harness, or at your main panel, before you start untaping things and pulling wire loom apart. If you are not sure if you found the right wire you can disconnect the other end and check with an ohm meter.

Hotrod,
That connector will fit the battery screw down terminal......
Been thinking about a long wire hooked to it and me and meter on the other end looking for it.

Sure looks like a ground wire to me. I'd use a volt/ohm meter. Set it to volts first and see if it's hot (pretty sure it's not going to be hot but best to check first). Then I'd set it to ohms and see if there is continuity between that and ground. If no continuity I'd hook it up to the ground terminal on the battery. And hope your inverter starts working. I assume you checked for voltage at the dc input terminals on your inverter?

I'd be surprised to see a bare ring terminal that size on anything but a ground.

Default more white wire

You guys got me thinking more about my wire and I have some more pictures, It looks like an add on... because of the black tape and two white wire of different gauge? And after looking at the pictures I have two large red positive one going to the switch and another over the top, I'll see if that is not my emergency gen start. In the next few days I will do some metering and hunting to see what cooking.

Thanks
