Engine Overspeed Do Not Crank. Apply DC power to the governor
system. After the actuator goes to full fuel, disconnect the speed sensor at
Pin 3. If the actuator is still at full fuel-speed then the controller is
defective.
Manually hold the engine at the desired running
speed. Measure the DC voltage between Pins
1(-) and 11(+) on the speed controller. If the voltage reading is 1.0 to 2.0 V DC check for:
• Speed set above desired speed
• Possible defective speed controller
If voltage reading is > 2.0 V DC check for:
• Actuator binding
• Linkage binding
If the voltage reading is below 1.0 V DC check for Defective speed
controller
Check Flywheel Teeth value. Incorrect number of teeth in setup.
Overspeed shuts down
engine after running
speed is reached Examine the Speed and Overspeed values for
the engine
Speed set too high.
Overspeed set too close to Speed.
Actuator or linkage binding.
Speed controller defective.
Overspeed shuts down
engine before running
speed is reached Check resistance between Pin 3 and Ground.
Should be 30 to 1200 Ω. See your specific Mag -
netic Pick-up data for resistance details.
Overspeed set too low
If the speed sensor signal is erroneous, then check the wiring.
Actuator does not ener-
gize fully Measure the voltage at the battery while cranking. If the voltage is less than:
• 7 V DC for a 12 V DC system, or 14 V DC for a 24 V DC sys-
tem check or replace battery.
Momentarily connect Pins 1 and 11. The actuator
should move to the full fuel position. Actuator or battery wiring in error
Actuator or linkage binding
Defective actuator
Fuse opens. Check for short in actuator or harness.
Engine remains below
desired governed speed
Measure the actuator output, Pins 1 and 2, while
running under governor control.
If voltage measurement is within 2 V DC of the battery supply
voltage level, then fuel control is restricted from reaching full fuel
position, possibly due to mechanical governor, carburetor spring, or
linkage interference.
Speed set too low
