no 12 volt or ac inside coach
First of all, I would like to apologize for not responding sooner. I fixed the problem that all of you graciously offered me solutions to try. This morning I solved the problem. As I mentioned earlier all 4 coach batteries were dead, as a result, 12 volts nor ac were flowing to the inverter. I checked the Transfer Switch and ac was coming in and out just not to the next point which I believe should have been the inverter. So yesterday and all last night I charged the 4 coach batteries. Then after they were charged I reconnected them and plugged into shore power and everything inside the coach (12 volts and ac) worked like it was supposed to. Why the 4 batteries died, I don't know. But I have a suspicion that the Trickle Charger that I put on about 15 years ago finally stopped trickling. So I am replacing the Trickle Charger with Granite Digital pulse charger, maintainer, tester, and batter plate cleaner. if anyone needs info on it go to granitedigital.com or jbtools.com which has a better price.
Thanks agisn to everyone for your input on my problem.
