2012 Keystone Cougar 29RBK - Electrical Issues - Battery Dying when Disconnect is OFF

[Drewandkaitlynwood]

Good afternoon, I am hoping someone can shed some light on an issue we are having with our 2012 Keystone Cougar 29RBK. We purchased this used in May, so it is basically new to us. We are having an issue with the battery dying when in storage. Here is what we know about it.

The battery is New with a sticker of 5/19 - installed by Camping World
The Converter is New - installed by Camping World when we bought it

We have taken it out 1 time - Memorial Day. We bought it beginning of May and had it parked at my in-laws' ranch until we hooked up to it to go camping. At that time the battery was dead. The battery disconnect was switched off - so that the battery wouldn't die...but it was still dead. I could not get the powered jack to raise the camper until I plugged my shoreline into a standard outlet using an adapter...At the time I didn't think much of it, other than maybe I forgot to switch the disconnect to the correct position when I parked it after the last use.

Fast forward to Friday. I went back to their property to hook up and pull the camper out and the battery was dead. This time I KNOW I disconnected the battery. I made sure of it. Yesterday, we installed a 30 amp circuit and a RV plug to the side of their house and plugged up the camper. The battery charged no problem, so my first thought was to have the battery inspected to make sure it didn't have any bad cells. We started checking connections to find that something was pulling 9 amps off the battery. With the main breaker off and ALL fuses removed, something is still pulling 9 amps. We tested it with the battery disconnect on and off.

My father-in-law is a jack of all trades and knows a lot about electrical stuff (thankfully so, because I do not. But I have a decent understanding). He is stumped. I am in the process of getting it back to Camping World to be inspected, but thought I'd ask on here if anyone would have a clue as to what could be causing this.

Also, now the powered jack will not raise, but only lower. It is connected to the battery, so I though maybe that was doing it, but we disconnected it and that wasn't it.

Thanks in advance, hopefully it's a simple fix.
