MH wont start on chassis battery. Has 13V
I have a 2008 Country Coach Affinity. It will not start (not even try to crank) on the chassis battery. Everything lights up on the dash OK, it even shows 13V on the voltmeter. Turn the key and not...

I purchased new battery post adapters to replace the old ones today. Cleaned all wiring up. Still the same problem!
While doing this I turned off the chassis battery. The dash is completely dead. SO obviously it is getting some power when the batteries are hooked up and on.
I fired up the coach with the battery boost and then took a reading on the batteries. 12.70Volts. If the engine is running, would you expect to see 12.7V or should there be a higher reading because they are being charged?
Also.. when the coach is hooked up to shore power, wouldnt you also expect a higher reading (something like 13.6) because there is no load on them and they are presumably being charged? (or maybe they are in taper/float mode so it wouldnt be so high?)
I am not sure what to do here.. the batteries were working fine and now they are not cranking the engine. They also dont seem to be getting a charge? But they are not completely disconnected because the dash sees them.
I am trying to find the battery charger and I cannot find it on the coach. I thought country coach had a dedicated charger for the bank. But could I be getting 12.7V and the batteries are too weak to crank the engine (nothing from the starter)?
