Master switches and charging in the Berkshire

Does anyone know for sure if the shore power will charge both the house and chassis batteries if both master switches are in the off position ?

Thanks.

Really don't know if you turn off the mater battery switches, but since you have shore power why turn them off. We leave ours on all the time just to make sure the battery are fully changed.

Well, I leave it covered all winter. To get at the master switches, I have to unstrap, and open the doors to get at them.
I was thinking about leaving it unplugged for every other week to cut down on the batteries cooking the water in the cells. I didn't want to leave the switches on so the batteries would hold the charge longer.

So I just thought it would be nice if I could leave the switches of, and simply plug it in for a couple days and unplug it for a time without having to kneel in the snow to get to the switches..

My coach stays plugged in at the house and I've never had a issue with the batteries cooking or leaking. I check them every three months and no issues yet

I was told by a guy from the FL hotline that only the house batteries charge while on shore power. I was under the impression that it also charges the chassis batteries.

This was the same understanding that I had on how the charging system works.

While plugged in, the house batteries charge first then once charged, you chassis batteries charge. You will know when the chassis batteries are charging because the aux switch on the dash will light up dimly and then flash. It charges the opposite way when the coach is running, the alternator charges the chassis first then the coach. I know this because my isolator switch that changes the charging sequence went bad and had to be replaced and they explained how it works.

As for the master switches being off, not sure if it will charge that batteries
