PRODUCT DESCRIPTION

If the panel meters show that the generator voltage is different from that of the bus, the voltage offset potentiometer may need adjustment. Make sure that the 

panel meters are accurate, calibrated, and at operating temperature. Most panel meters are accurate to ±3% and are not temperature compensated.

Benefits:

Prime mover will 

not accept full 

load. 

Is the governor at full 

fuel? 

YES—

1. Is the linkage adjusted properly? 

2. Is load excessive? 

3. Is the voltage regulator (if used) set properly? 

4. Is the fuel stop on the prime mover set correctly? 

NO—

1. Is the load limit out of the way, and adjusted properly? 

2. Is the fuel limited (if so equipped) set too low? 

3. Is there adequate air pressure for the fuel limiter? 

4. Is the linkage sticky or improperly adjusted? 

5. If electric start fuel limiter—is there adequate voltage for the 

solenoid? 

Needle valve 

adjustment does 

not eliminate 

instability. 

(1) Are the oscillations 

periodic and smooth 

(not intermittent)? 

YES—

 Go to question (2). 

NO—

Check the following: 

1. Is the fuel source adequate and constant? 

2. Is the speed setting reference steady? 

3. Is the governor oil level low? 

4. Is the load erratic? 

5. Is the governor oil clean? 

(2) Is the frequency of 

the oscillation above 5 

Hz? 

YES—

Check the following: 

1. Governor drive train. 

2. Governor alignment. 

3. Dirty spring-driven oil damped ballhead (if so equipped). 

4. Bad injector or misfire? 

NO—

 Go to question (3). 

(3) Are the oscillations 

related to speed setting 

variations? 

YES—

 The cause of the speed setting variation must be found and 

corrected. 

NO—

 Go to question (4). 

(4) Does the oscillation 

disappear when 

blocking governor 

output or operating 

hand throttle? 

YES—

1. Is linkage loose or worn? 

2. Is governor part number correct for this application? 

3. Replace governor. 

NO—

1. Check for load fluctuations. 

2. Check fuel supply. 

3. Check for loose or sticky linkage. 

When blocking governor output or operating the hand 

throttle, the system is not under governor control, and 

extreme caution must be taken to prevent overspeed. Do 

not attempt if overspeed speed device is not functioning. 

Governor will not 

shut prime mover 

down. 

Is governor at minimum 

fuel position? 

YES—

 Linkage is improperly set to allow shutdown. 

NO—

1. Is shutdown actuation signal available at the governor? 

2. Are shutdowns properly adjusted? 

3. Is shutdown strap in governor properly adjusted? 

4. Close off fuel and replace governor.
