Hello, this is owned by a new tenant on my property. I’m trying to help her with it as she has very little experience with RV living.
Her battery is dying while connected to shore power (which is correct amps and fine). If I put an external charger on it, it’ll stay working for the most part.. it’s been a bit finicky when the charger thinks it’s done, it’ll stop and then will proceed to die again. I’ve looked everywhere that I know to look for the converter and it doesnt seem to be anywhere near or behind the panel. I’ve looked behind a few other panels inside but it’s just not turning up. Does anyone know where it is???
I’m hoping there’s only blown fuses on the back but even if the unit is bad, I can help her get a new one. Any help would be appreciated.

I am working near southeast Tucson and mostly just cleaning up the area to be used as a campground. The civilian conservation corps was active here for many years building up the park infrastructure. As I was crossing a wash, I noticed it was full of glass shards. I followed it up to what looked like a mound that was slightly different than the ground around it. I recognized it as an old landfill and dated some of the bottles to the 60s and maybe older. The wash has been slowly carrying pieces of bottle for a mile or so which means there must be a lot still buried. Today was the first time I dug down a little and pulled out a few in tact ones. I just need to get them cleaned up to see what I’ve got.
