Battery Draining
We have a 2019 Montana High Country 321MK. I remove the battery and store it in the basement of our house, charging it periodically over the winter. When we took it in for service in December, I installed the battery and got a low battery warning the next day when I was unhitching at the dealer. It went from the charger to the coach. They looked at it and said it was a bad battery and needed replacing (after 2 years). Had seen no issues with the new battery at our seasonal site until this past weekend when the awning wouldn't retract when we were leaving. Troubleshooting it I started at the awning motor and got 4.0 VDC. Traced that all the way back to the battery (probably should have started there). I have the battery on a charger right now, but where should I look to see where the drain is or why it isn't charging? Electrolyte level is good. I am getting around 2.0 - 2.4 VDC across one set of the wires leading to the battery. Is this the charging current? I don't want to park it at the dealer for weeks to get it looked at, so can I externally charge it for the summer?
Sorry for rambling. Looking forward for insight on what and where to check.
