Inverter and charging system problem (andy)

[brania]

it turns out the inverter squeal was just a symptom of the problem. low battery caused the warning sound.but the real issue is as follows:

we are plugged in to shore power ( 30 amp)
we have a trik L start battery maintainer hooked up and has always worked properly for over a year.
last night we noticed both coach and house batteries are totally discharged.
I ran generator for over an hour and got no bump at all to the coach batteries.

in the past both sets of batteries remained charged when plugged in to shore power.

i am at a loss to explain these electrical issues.

does anyone have a suggestion?

thanks

I'm like sergeant schultz- I know nothing!
But I'll suggest you post your make/model coach so others might better diagnose
your problem....
