All batteries drained
3 weeks in storage ( I have gone much longer ) and all of my batteries were drained, 2 house and one engine. I had to jump the engine battery, then started the generator. The engine battery took a long time to reach a level sufficient to start the engine again.
I am sure I engaged the "store" setting, but what would cause the engine battery to be depleted along with the house system.
I am back in storage with full charges around, and will check it in a week or so. After the winter shut down I will be replacing every battery, and hopefully upgrading in the process.
It has me considering a small solar unit to maintain the engine battery at least.
