Battery Charging woes
Bought 2 new deep cycle 12V coach batteries in March. We went on a 1 week dry camping trip in July. Ran the generator for probably 2 hours per day on that trip. The batteries steadily discharged...

Thank you for the replies!
Don't know the brand/model of the converter. I have manuals for everything in the MH except of course that. I need to dig in there and look at it.
I will connect to shore power with batteries disconnected and test voltage, then report back.
Battery cables are not backwards.
I "feel" like the converter is under charging. As stated it should be 13.6 while charging and it isn't.
But I also thought that the converter would either just work or not work. But I suppose that is not the case. It is charging, just not high enough voltage???

The 'charger' output while on shore power or generator is low.....
Connect to shore power for a few hours
B1 12.6 B2 12.6
Disconnect shore power, connect and run generator
B1 12.7 B2 12.67
You are seeing higher voltage when running engine.....but the charge line is small so charging of batteries would take hours.
Need to test 'charger' output with battery cables disconnected.
With 110V AC power in.....charger output should be 13.6V DC. Anything less 'charger' is not functioning properly.
Also check that you didn't connect battery cables backwards and the 'reverse polarity' fuses on converter/charger are blown.
If they are blown the charger output can't get to batteries.
