Do you know if these voltage readings normal?
How long after you unplugged did you check the house batteries? There will be a discharge rate from all the house circuits that normally stay energized that will draw them down after a time.

1 minute. When I tested it read 12.8v then dropped to 12.02v and stayed there.

12.8 volts, with charging going on, is a low battery. You need to plug it in and give it 4 or more hours, to get it up to over 13.6 volts.

Then you can pull the plug and test the voltage. If it drops below 12.6, in a minute, then they are shot or something drawing lots of power is on.

Travel8,

you just answered 2 of your 3 questions you originally asked. While plugged into shore power (and generator) you ARE getting charge to both your house and engine (chassis) batteries. This is good.

Unfortunately, I too agree that you may have an issue with your house batteries, as as soon as they are disconnected from a charge, they are dropping to 12.02 Volts. They should be, as stated above, closer to 12.6V immediately after disconnecting from shore power.

Good Luck!

Thanks, will have them tested.

Do you know of anything else other than something turned on in the MH (no major appliance, etc was on when I tested that would have resulted in a heavy/moderate load) that would draw lots of power?
