First post a fellow tech turned me on to this Forum! I have an Error code 102 "Drive Transistor Regulator Internal Error" LED 4 (red) "Fault In Reference Value Circuit" that is giving me fits. I have run through the diagnostics in the manual for the problem to no avail. All the values are within specs. The symptoms are: When going forward or backward the lift locks out (E102). If you very slowly accelerate you can some times get to full throttle without lock out. With the drive wheel jacked up off the floor (no load) you can can accelerate through the full range forward and back without it tripping a code and locking out. Any help would be much appreciated!
