OK...here's what it is. Looks good to me.
13.45 on 120 a/c
13.76 with engine running (Alt charge line)
13.20 with generator running
Those are not good voltages at all.
The link that Old Biscuit posted is very worth while if you have Parallax-electronic series 7300. I saved a copy on computer and printed out a copy for "my" RV's owners manual. Couple big clues to me were that several suggested in their posting, no big deal about higher voltage.
High voltage IS a big deal- it means the unit is not working correctly, which is reinforced by the voltages you measured.
I predict you will shortly be buying yet another battery.
