Working on a 7BRU23, I changed the print board display but now I lost the reach/retract function. Configuration C8 is No Straddle, Tuning C5 is two speed, Both solenoids are OK, Voltage are ok 22v, but Lift Amplifier turns pump only between 9-12% RPM. All other aux hyd functions are OK turning pump at 30% RPM. Scanning pulses I can see the signal arriving ok to LPA. Does anybody some idea about this trouble? Thank you
