started as Fault 10, 20 did checks found shorted D1R on right motor drive circuit.  Replace both D1R diodes for Right and Left motor circuits.  Now Fault 13 checked IGBT's found Right one shorted, swapped Drive IGBT's had fault 13, 23, returned to original postion back to fault 13.  Replaced IGBT for right motor still have fault 13, checked continuity to right drive armature circuit have continuity, checked driver board test correctly, checked CN1 continuity test, checked ok, checked CN2 continuity test, checked ok, current sensor wiring to logic card test ok, checked voltage at CSR 4Gr had 15 volts, checked voltage at CSR 2BrY had 5 volts, checked voltage at P3-45 of Logic card had .21 volts, checked with direction selected, press accelerator, unit faults as soon as accel switch closes.

Is the fault in the Logic Card ?  When diodes short out does it take out Logic Card ?  Anything else need to be replaced along with Logic Card, Bridge Card, Driver Board.  Just want to be sure the Logic Card is the problem.  Thanks, J
