Batteries not charging-both engine and coach

[Pete Masterson]

How long was the coach 'off power'? It might be that the batteries were discharged to a level where they are beyondresuscitation.

It is also possible that the batteries are so low that there isn't enough power to trip the relay. I think someone said it takes a minimum of 10.8 volts. (If you're below 10.8 volts, see he first paragraph.)

Finally, try putting a portable charger on the engine batteries (or the house batteries) to get them up about 11 volts so the relays will operate.

My batteries wont charge after I found them discharged.grand kids knocked shorepower plug out. I pluged it back in and a couple of days later they are still dead. I have the diagrams for the chargeing circuit. There are four bosch relays in the circuit to allow the current to the buss and then to the battery bay. One of the wires that goes to the coil of one of the relays goes to the front elec panel.What else is neccesary to charge the batterys.relay or whatever.I have been working on this for two weeks with no results.
Anyone have ideas or knowledge of this circuit please advise?
thanks in advance
