Converter fan runs constantly
We recently purchased a 2013 Z1. Our first trip out was fine once we determined the hot water heater had a bypass valve which was not specified in the manual. After we found the access panel and got the water turned on we had no problem. Once we got it home, we plugged it into the 30amp power outlet we have in our garage. We noticed a few days later that the converter fan was running but nothing was on inside the camper (no lights switched on, no refrigerator on, no AC on...nothing electrical was turned on or running). I checked the deep cycle battery and noticed that it was low on water so I filled it up. Would the battery being low on water trigger something that would make the converter fan run? We're kind of new to camping but I don't see why the battery would make the fan run.
Anyone have any suggestions or solutions to this issue?
