Issue: The Auxiliary Battery is discharging for an unknown reason. The electric display unit is showing the battery is in operation despite the fact that the auxiliary battery users (fridge, lights, sockets, water pump) are all off.
I have already performed some trouble shooting by removing the the fuses for the above mentioned items one at a time from the auxiliary battery fusebox. Even with every fuse removed (except for fuse 1 - the electric display unit fuse) the display unit continued to show the auxiliary battery being discharged.
Nothing extraordinary has happened, but two things come to mind. 1) I gave someone a jump who had broke down in Tofino. 2) I had the van plugged into a friends outdoor socket, when we woke up in the morning the van was no longer charging, I did not investigate but assumed that the van just caused the GFCI to go off in the middle of the night.
Where to check next? The camper manual mentions a potential auxiliary battery discharge from the use of the city water system, although the explanation is short and tough to decipher. I have never used this system before and the battery has been functioning fine all summer until now. I am thinking this might be a red herring.
I appreciate any help someone may be able to give me. I have not been electrically inclined, but want to get my hands dirty and to the bottom of this issue. Thanks!
