Number one thing to check !

Are your house batteries hooked up correctly. If not hooked up by an RV dealer probably wont be. ( not going to guarantee a dealer will do it better but you can hope)

You can tell very quickly if they are wrong with a quick check. provided we are talking about 4 6 volt house batteries. Two of the batteries will have a cable going from the Positive post on one battery to the negative post on another. If you do not have that then you only have 6 volts to your system.

That will give you all of the symptoms you are talking about

Something like this comes up pretty frequently on the forum. In cases where the owner just changed out the battery, it seems to always turn out that the batteries are connected wrong.

You have not mentioned a volt meter. Do you have one and are you using it?

Ok problem resolved, and of course as is usually the case with me it was operator error.
After spending a full day with an electrician friend testing every connection, removing and reinstalling the batteries twice we suddenly noticed a bit of yellow on one of the cables. Pukked everything apart and cleaned all of the cables with WD40 and voila the cable with a yellow stripe was a RED cable,not black so I was hooking it up to the ground instead of the positive. DUH
So lesson learned, one when in trouble get out the wiring diagrams and clean the grease and crud off of the wires so you can see their colors.
Oh yea remember in my first post I asked about the 4 wires to the ground or negative, well it is only three.
All is well for now until I find out that I fried something in the process.
Again thanks for all of the suggestions.

I am glad you found your problem. Just for people that read this post. I have not counted them but I would imagine there are over a 100 wiring diagrams in this Forum that tells how to hook up coach batteries and not depend on color codes of the wires. When you take out your batteries Make sure you hook them back up and check them with a wiring diagram. LIke the OP dirt and grease can make all of the cables black. If you hook them up with a wiring diagram for a guide you wont have to spend hours troubleshooting problems.
