• Input voltage at P7 should be less than
0.9 volts. Adjust or replace accelerator
unit to insure that the voltage at P7 is less
than 0.9 volts before depressing pedal.
Defective potentiometer. Verify correct
operation of potentiometer, and replace pot
assembly, if necessary.
Open circuit at P8 or open potentiometer
wiper at P7 – verify continuity of wiring at
