There is a breaker next to the battery at the back side, use a flashlight, see if it's tripped. At least on mine there is one hiding behind the battery and for the battery. Mine is also very hard to get too as I got these big oh batteries in the way :0

More than likely the problem is what YosmiteBob mentioned, the breaker behind the batteries.

The reason why I asked the model coach is even though we all have the same general breaker it can be mounted in different locations and sometimes is difficult to see.

Some folks have reported that the batteries tend to slide within the battery box causing the breaker to trip and have described using some type of spacer between the battery and the battery box to keep the problem from happening again.

It is a 150 amp breaker not just a small one at that.

Not exactly sure how I did it but all is working, I must have connected the batteries wrong when I installed the new ones,, started over and blew some fuses but I am back in business. Thanks for all the ideas I know much more about my 12 volt wiring than I did 2 weeks ago.

Rookie question here,

Does the 12V system switch need to be in USE position to charge the house batteries when on shore power?

Thanks,

Just ran shore power to the Vegas last month and with all the fun I have had with House Batteries (replaced Harris Batteries) I want to be sure that I do all the maintanence, water levels and other things correctly.
