Stored my camper & truck under the carport last winter. Started & ran the truck a couple of times just because I thought I should. I kept the camper DC breaker knob pushed in (off) all winter. Truck has been idle the last couple of months. I tried to start the truck but this time the battery was drained. All four meter lights in the camper light up, indicating camper batteries are fully charged. Are the camper batteries sucking all the juice out of my truck battery?
I put a charger on the truck battery but it behaved erratically and overheated. A rapid clicking sound started coming from the space in the truck bed between the camper and the truck cab. What could that be? I thought the only thing in that space was the plug connection from the camper to the truck battery. Clicking was not audible from inside the camper, nor was it coming from anything inside the camper battery compartment. The clicking stopped when I disconnected the lead from the truck battery to the camper. Reconnecting the lead caused the clicking to start again. I left it disconnected and then I was able to charge the truck battery. Once the truck battery was charged I reconnected the lead to the camper battery and everything appeared to be working fine again.
The truck sat idle for another week and now the battery is drained again.
I bought the camper new in 2014 and never had this issue before. If the battery separator is that dubious I think I might just have a separate alternator installed just for the camper batteries.
So what do y'all make of this?
Thanks for your input.
