This one has me stumped. Drive wheels on the ground, the maximum SCR output at the drive wheels is 40 Amps and 9 volts. Will the kick into bypass. raise drive wheels off the ground, goes smoothly to 36 volts and 115 Amps. Self diagnostics says all components pass. switched logic card, no change. checked driver board, ok. tried different accelerator card, no change. readings to both motors the same. Not sure where to go from here. Any suggestions would be appreciated. F30 S/N 5DB2168.
