Chassis battery issue

I have a 2014 Winnebago sightseer. During the summer I have it parked at my cabin and plugged into 50amp shore power 24x7. After being gone for a couple weeks, I came back up and my chassis battery level basically drained(It's less than a year old). I know that if I store it, I need to switch the coach and chassis batteries off. But I thought as long as I was plugged into shore power, the chassis should keep a charge. The coach battery is normal. I was hoping to start the unit using the battery boost switch and charge the chassis battery, but that wouldn't work either. SUGGESTIONS appreciated....

THANKS

You got it backwards
The converter charges the COACH battery.. now on a 2014 it should alo charge the CHASSIS but.. with the coach batteries off. it might not.

Your voltmeter is your friend. Use it to measure voltage AT THE BATTERY TERMINALS

After 2 hours without charging 12.x is good. the .x determines the state of charge (Without double checking I think .6 is full)

With the converter connected and charging 13.x is common.. NOTE depending on your converter it may go up and down so try mulitple readings over say a 30 minute period...

Also. WHAT is the converter model. in some Rigs this is the power center model In others. the converter is a in a different place (Mine is)
