DECISION
No - Replace engine speed RPM switch. (WP 0095) Verify problem is solved. (Step 7 - Does engine increase
RPM normally?)
Yes - Go to step 4. (Step 4 - Is wiring between governor controller and governor actuator free of damage and
connected properly?)
STEP 4

CONDITION/INDICATION
Is wiring between governor controller and governor actuator free of damage and connected properly?
DECISION
No - Properly connect harness connector and/or replace wiring between governor controller and governor
actuator. (WP 0132) Verify problem is solved. (Step 7 - Does engine increase RPM normally?)
Yes - Problem not found and may have been missed or overlooked. Repeat all previous steps in this
troubleshooting procedure. Go to test 1. (Step 1 - Is problem with engine speed present when using main control
panel?) If problem still exists after all troubleshooting test have been accomplished, replace governor
controller. (WP 0092)
STEP 5
Are less than 200 ohms measured from red/white wire at engine speed RPM switch to interconnect terminal
strip, terminal 4?
1.
Ensure multimeter is set to measure continuity.
2.
Connect red multimeter probe to red/white wire at engine speed RPM switch.
