up date,....while standing in the coach staring at the monitor... I watched it go up to 13.4, when that happened, the clunk sound of a latching solenoid , and then the chassis battery went up to 13 volts... so what i'm thinking is now it will top off both coach and chassis batteries…. while plugged in to shore power, and with the batteries so low, it only was charging the coach batteries till they reached 13.4 volts...correct????
