chassis batteries

[Michael Brody]

I have an odd problem (I think). On my '97 40' BMC, I came home from 2
months in Florida in mid-March and plugged the coach in to the house on 15
amp service.

A month later, I noticed the genset auto-started. The house batteries were
showing fully charged and the chassis were too low to turn the starter over.
The genset is set for auto-start for low-battery. All the batteries are
new.

Questions:

1. Is the auto-start function supposed to work for chassis batteries or
just house?
2. What ancillary load is on the chassis that would kill the batteries in a
month?
3. Is it ok to leave the dash switch connecting house and chassis batteries
in the "on" position when plugged in, or will it cause damage through
overcharging?

I was at the Birdsnest in March and had the inverter panel and auto-start
functions set-up.

Your suggestions would be appreciated.
