Batteries not charging-both engine and coach

[Chuck Wheeler]

Ed,

I'm not too far away if you are not comfortable checking this out. Pete may be right if the batteries were taken to zero or are fairly old they may be beyond recovery. We can be optimistic. I have forgot to turn off both battery switches and discharged my Trojans twice and they have come back. I have a little over Six years on them and just had them checked by the dealer and he said there was no reason to replace them yet.

I think that a clue to my problem, since it deals with both seperate banks of batteries. I have also tested the battery isolator. I have exausted my ideas.
