Chateau 28Z wire q?

[Myron Nelson]

I have a 2018 Chateau 28Z

Coiled behind the battery bank under the entry step hangs a loop of flexible conduit encasing a single yellow wire with a bare end and no terminal.
Anyone have any idea what that is for?
Thanks in advance.

Check the positive post/s of the battery/ies to see if maybe a terminal from that wire pulled off or corroded off.

I don't know much about your coach. Is it pre-wired for solar? Ours uses an 8 gauge yellow wire (also a white).
