I had posted an earlier thread in December 2013 about a 12 volt problem and I thought that just replacing both batteries had solved the problem BUT now I have 2 dead batteries. Here's what I have so far:
-what appears to be a bad alternator -meter is supposed to show a 1 volt increase to the 12.4V fully charged engine battery when the engine is running which indicates that the alternator is good.....no increase at all so MAYBE the alternator is bad?
-when plugged into shore power, the Parallax controller should allow the house battery to charge but no charging is taking place.
-the switch that allows u to isolate the 12 volt system doesn't work consistently....I have to toggle it several times and then I can -sometimes- get it to go on (use).
Is it possible that I'm looking at a fried charging system? Any and all replies are greatly appreciated.
