Motorhome will not run on batteries

Glad you solved that. Take note of the issue of not letting those batteries get below 12.2 or you will start this again.

You might want to post what converter you have. An older style should probably be replaced. Early ones killed batteries if left connected.

Our next thing is not an easy fix, we have some water damage to a part of the floor at the drivers door. For this one, we are letting the professionals take over. Taking it in for an estimate after our next trip out in September.

I do not like to leave people hanging who have been so nice to help, and I did not finish this post off. New batteries and all problems disappeared. On to the next fix. Thanks again.

Dh is working today, but we have two new batteries ready and waiting. Our son brought something up after getting back from inlaws cottage...and they tested the liquid level in batteries, none, my husband said, they did add, but son says they are more then likely toast. As a poster said each time we saw the motorhome it was plugged in. It is old, we know that, but was in complete use last year. She is a little rough around the edges, but we are making her ours. With help from all of you...(Sally) Thanks

You need new batteries.....Dennis

After reading this post as with the others that you have posted recently, it appears that you need to change your batteries and a lot of your problems should go away. JMO

As in most of the 12 Volt system problems, the first thing to check is the condition of the batteries. If the batteries are discharged any tests that you attempt will not be viable until the batteries are recharged or replaced. So take care of that batteries first and then see if things work. If things still don't work, then do all of the checks posted above. New or charged batteries first, then trouble shoot second.

The store/use switch is the battery disconnect. Press it one way or the other and listen carefully for the click of a relay burried in a cabinet someplace likely near the battery.
If the battery is completely dead you likely wouldn't get the click.
In the "use" position the battery shoudl be connected.

My bet is dead battery.
I'm also in a new MH, had it a week and just yesterday took it in for a warranty battery replacement.
Letting a battery run down lower than 70% to 50% is a killer of batteries.
These things sit on dealers lots and are neglected. Salesmen leave the lights on accidentally when the show them, and they will sit discharged for periods of time.
I knew this going in but was unable to really ceck my battery since they had it plugged in and charging when i showed up for the PDI. In my case, it didn't tak long to confirm that my fears were correct.

Take apic of how the bats are connected, so you can reconnect them that way and label your cables. Take the batteries to a local auto parts store and have them tested.
