Short Somewhere?

[dwava]

I'm new here, but here's a question?
I have a 2010 Coachman Concord B+ on a E-450 FordCH.and I'm having Battery problems. The Vehicle battery has a draw from ?( so says Ford),
but the battery is good, and the alt. is good, but battery will only stay up for a couple days. Coach battery is fine. Ford says it has a draw from the coach, service at place of purchase says it the battery??No draw from Coach! I'm getting ready for a trip and I'm worried about stopping overnight, any comments or thoughts?
Thanks

Dwava, I run a battery minder on my coach battery all the time even when I am plugged into shore power at a campground. This helps to keep my automotive battery up.

Being plugged in doesn't charge the automotive battery but the coach batteries should get charged.

If you can have a battery disconnect (knife switch) installed on your automotive battery and that will prevent you from drawing the battery down. You should have the draw tracked down to see what could be bringing your battery down so quick It should normally last for more than 2 days even with the parasitic draw that RV pull off the automotive battery.

Until you find out what the problem is, I suggest you get a battery knife switch. That will keep you from discharging the battery. My neighbor that has a class C had to replace her battery because it was doing the same thing. She had a bad cell and replaced the battery, now no more problems. If you use the knife switch and the battery is still bad you will know for sure it is the problem. One should cost less than ten dollars. If it is not the battery you will still be safe to go, only open switch when stopped for any length of time.

Thanks for the comments, I'll look into the knife switch idea.

You can even get a remote controlled cutoff switch. They aren't too expensive and will avoid you having to open the hood each time you want to start the engine.
