I'm horribly inept when it comes to electrical stuff. Like the worst.
In the store position there is still considerable parasitic drain that will drain the batteries in a very short time. (varies from coach to coach and model)
I have never really figured out why the use/store switch even exists because there is still a drain on the batteries!!!
If you were plugged in and switch was in the use position your batteries should be charged, need to check your charger output.
