UNSATISFACTORY PERFORMANCE
SYMPTOM NORMAL READING PROBABLE CAUSE OF ABNORMAL READING
Actuator does not
energize fully
1. Measure the voltage at the
battery while cranking.
1. If the voltage is less than:
a. 7V for a 12V system, or
b. 14V for a 24V system,
Then: 1. Check wiring
2. Check circuit protection/relay
3. Check charging system
4. Check battery
2. Momentarily connect Terminals A and F. The
actuator should move to the full fuel position.

5.
Actuator or battery wiring in error
Actuator or linkage binding
Defective actuator
Fuse open. Check for short in
actuator or harness.
Check START FUEL and CRANK
Engine remains below
desired governed speed
1. Measure the actuator output, Terminals A & B,
while running under governor control.
1.
2.
If voltage measurement is within 2V DC of the battery supply voltage
level, then fuel control is restricted from reaching full fuel position, pos-
sibly due to mechanical governor, carburetor spring, or linkage inter-
ference.
Check SPEED, IDLE, GAIN, START FUEL, and CRANK

SYMPTOM NORMAL READING PROBABLE CAUSE OF ABNORMAL READING
Engine Over Speeds
1. Do Not Crank. Apply DC power to the governor
system.
1. If the actuator is at minimum fuel position and there exists an erroneous
speed signal, then check speed sensor.
2. Manually hold the engine at the desired running
speed. Measure the DC voltage between Termi-
nals A(-) & F(+) on the speed control unit.
1.
2.
3.
If the voltage reading is
1.0 to 2.0V DC:
a. SPEED parameter set above desired speed
b. Defective speed control unit
If voltage reading is > 2.0V DC then check for:
a. actuator binding
b. linkage binding
If the voltage reading is below 1.0V DC:
a. Defective speed control unit
3. Check #TEETH parameter. 1. Incorrect tooth count entered.
Over Speed shuts down
engine after running
speed is reached
1. Examine the SPEED and OVER SPEED oper-
ating parameters for the engine
1.
2.
3.
4.
5.
6.
SPEED parameter set too high.
OVER SPEED set too close to SPEED.
Check SPEED RAMP parameter.
Actuator or linkage binding.
Speed Control unit defective.
Gain too low.
Over Speed shuts down
engine before running
speed is reached
1. Check resistance between Terminals C&D.
Should be 130 to 1200 ohms. See specific
Magnetic Pick-up data for resistance.
1.
2.
OVER SPEED set too low
If the speed sensor signal is erroneous, then check the wiring.
