Hi everyone!
Today I found out that my coach battery isn't charging... I replaced my battery isolator this summer and I thought the problem was solved. But it's not!
The problem is weird. I made some drawing to explain it to you. What is weird is that when I'm plugged into AC power, I get 14V to the isolator at the side of the coach battery. But when the engine is running, I get 14V too, but it doesn't get through to the battery... I don't understand why when plugged into outlet the 14V would get to the isolator, but when I'm using the engine, the 14V won't get to the coach battery....
It's only working one side. Can anyone tell me what I should looking for??
Thanks!!
