I went to the coach today, been a while due to the covid. I have not driven it for a couple of weeks. I switched on the disconnect for the batteries on the house and the control panel start blinking crazy.
I disconnected the shore power and it stopped. I think the house batteries are dead at this point. I don't think the battery charger was charging them while it sat. The coach batteries are ok, and the motor will fire right up. Do I have a bad battery in the unit or is my power switch going bad?
