when should a powermax pm4b drop into float mode

Hey everyone... hope your summer has been as enjoyable as mine. (...loving the cooler than normal weather!!!) I recently installed a new pm4b 75amp charger and Trimetric meter. My batteries are 4 T...

Regarding the pm4b mod:

FYI...the initial voltage at the screws was 14.6+ volts, not 13.6. (this immediately concerned me, and i wasn't surprised when it still kicked into abs)... but now i'm wondering if it will still float charge??? hmmm.

and i may have to re-goop that little screw pot, just to be safe.


update: doesn't look like the float mode works. starting with 12.81v batts, i took one bank down to 1.2a at 14.15 Vabs for over two hours.
