My wife and I recently bought an Aliner 2016 Classic (used). I knew the battery was dead when we bought it so we didn’t test the things that ran off of the battery - or anything with the shore power disconnected. (The battery was actually low on water so the seller filled it with distilled water and we gave it a shot to see if it would come back to life after towing it with the TV and having it plugged into a 120V source for a while). We took the camper out last weekend for our first trip and to see what works and what needs repair (loved the platform and got a pretty clean unit and a good price so we’re happy). Here is what I found and I’m trying to get some more information about wiring, etc. to figure out how to resolve my core issues with the 12V battery system: 1. The “old” battery was blowing the 20A fuse that runs to the positive terminal when shore power was connected and it was being charged. I disconnected the battery as I figured there was some type of short in the battery and had it tested (dead). 2. When I put the new battery in it seemed to charge OK (no fuse issues). However - when I disconnected shore power and tried to run some of the 12V stuff (lights) they didn’t work. I was doing this at the campsite so I wasn’t sure the battery was charged. I put the battery on a tester/charger when I got home and it is charged - so there’s something that’s keeping the battery from connecting to the 12V loads. ???? (Fuses at the battery and in the panel are good). 3. I disconnected the battery and tried the lights (no shore power) while I was hooked up to the TV - and they worked. I don’t know if the connection of the TV is different from the battery - I.e. I haven’t traced it back to the panel - but I’m wondering if this indicates something to anybody out there? 4. We used to have an RPOD - and any 12V load worked - even with the auxiliary battery completely out of the circuit (disconnected). Is this the same for the pop up - I.e. the converter will supply the 12V to the load (since our lights we running I’m thinking “yes”)? Thanks for whatever insights you can provide. We liked our RPOD but we think that the pop up is going to be great for us. A lot more floor space and more aligned with the type of camping we expect to do.
