so the 1st time saw this unit i checked the battery level and found it was 24.7 volts and the BDI reading 88%, so i checked water levels (good), i proceed to main contactor. checked across it 24.7v in but only23.5v to pump contactor and 24.7 at positive at connector and B+ on controller and no problems with wiring to ETAC card. but when i double tap master switch, code goes away truck runs normal and 24.5v across contactor. but when you shut off switch at let set for a minute & turn back on code comes back on same readings, i changed the cocntactor no change, put a charge on it 25.6v but BDI still read 88% and controller heartbeat remains steady even though the code is active. i am wondering if it is the controller is the problem?
