Electrical Control Circuit
Note 1: To test the key switch must be in the START position and foot pedal in neutral.
Note 2: Before troubleshooting check the F4 (15 amp) circuit breaker location under steering column.
Note 3: Check for 12V at the F4 machine circuit breaker. If no input voltage at the GRN/BLK wire, repair or replace wiring or key switch.
Service Adjustment Note:
A drive pedal sensor setting that is set too low will not target (match) the drive pedal neutral return position (dead-
band too narrow) and the engine will not start. Too high of a setting will increase the neutral range (dead-band too wide) and delay the activation
of turning on the auto sweep and scrub functions when the drive pedal is moved out of an excessively wide programmed neutral range.
Note 4: A new pedal sensor must be programmed for its neutral position and dead-band setting, follow instructions shown on this page.
