6am on monitor 10.6- off- o o A- 0 W -1.8V (20 -24.) 0 KWH , all means nothing to me.. maybe to you???
Just saw this thread come back alive...I assume you have two AGMs [2x 75ah ?] and that this is a FWC....if that "10.6" or previous "10.2" is the voltage shown for those batteries, then my guess is that they are either dead-right-there or severely damaged...Vic is correct, a picture of your BMV monitor?
If they are damaged or dead like Vic said why? Most likely insufficient charging and/or excessive draw down..
Suggest testing the voltage on each battery separately and then charging each with a stand-alone battery charger; but then if nothing shows up, take them into to battery shop for a load test...voltage alone may not show a weakness...
These are just my WAGs...sorry for your fix!
