Not charging, New House Batteries

Please Help! I had 4 new house batteries installed while I watched at a highly recommended battery business yesterday in Missouri. My Magnum inside computer reflected proper voltage but 0 amps charging. Everyone thought it would kick in but 550 miles later and the generator running full time, the batteries are half charged and going down. I am stuck because there is not enough juice to operate the hydraulic levelers or slides. The Magnum always reflected a few amps for standby charging to up to 80 amps for a short time after a severe usage drain. There were no sparks or anything unusual when the nearly five year old batteries were replaced. This is in a 2011 Forest River Charleston. I believe it has to be something simple (yes I know that sounds stupid in the RV world) like a breaker or fuse. Any thoughts or ideas on how to troubleshoot this problem would be greatly appreciated.

Check your battery disconnect switch, also known as the salesman switch. Might be by your door/stairs.

Look closely for a wire that may have been dropped and not reconnected.

As an emergency setup you may be able to start your engine and hold the emergency start button that combines the battery banks to get a bit of a charge going and to get the jacks down if needed. Not a good idea to completely charge heavily discharged batteries that way so don't do it for long.

Thank you for your replies. In the end it was simple but not visible. One of positive battery cables and subsequently both separated from from the copper connecters to the batteries. This was not visible because there is very heavy heat shrink vinyl/rubber covering the connector to the bolt hole and about 2 inches back down the cable. Nothing was hanging down or visibly out of place but the crimping on the cable connecter was not very good and did not hold it on the cable. Thus there was no connection even though everything looked right and was visibly connected.

I don't know where you get that heavy rubberized heat shrink material but I would love to have some. The only thing I ever see is that paper thin stuff from the auto parts stores.

Thanks for posting the cause of your issue - it helps all of us when we know how you resolved it.

I check my batteries with my Fluke meter almost everyday. Call me OCD, but I would rather find a probelm early. Once the battery bank is discharged excessively, it's irrevocably damaged. Batteries are expensive!

So much for the highly recommended battery business. They should have caught that right away.

Glad you got it going and thanks for coming back with the solution.

I am not sure that I have seen a "Thick" shrink tube, but there is nothing that prevents you from putting on 3 layers.
Put on the first, and shrink it, then the second, and finally the third.

HOWEVER....this is an edit...I did a search for "Thick Wall Heat Shrink" on ebay.
Found several...not cheap...
