Batteries won't charge on shore power - but DO on Generator??
So, what could cause the batteries to NOT charge on Shore Power, but DO charge on Generator (and/or engine)?
MH has been sitting, on shore power for a month or so since last trip. I find the batteries dead. The 110v ac system works (slides work), but the steps dont work. I disconnect from shore power, start the engine and the batteries charge. I start the generator, stop the engine and the batteries charge.
side note: these are the "stock" batteries from when I bought the MH "new" in early 2018 - and they've been completely drained a few times since. They dont hold a charge very well. I do plan to replace them with new AGM deep-cycle.
