4. Open or shorted field windings

1. Faulty capacitor

2. Engine speed is too fast

1. Open diode

2. Engine speed too slow at full load

3. Excessive load applied

1. Unbalanced  engine

2. Dirty, corroded, or loose wiring

connection

3. Unstable load applied

1. Loose generator or engine bolt

2. Short circuit in generator field or

load

3. Faulty bearing

1. Adjust engine speed ✽

2. Referring to the wiring diagram,

clean and reconnect all wiring ✽

3. Replace capacitor ✽

4. Test winding resistance, replace

field winding if necessary ✽

5. Test diodes, replace if necessary ✽

1. Adjust engine speed ✽

2. Test diodes, replace if necessary ✽

3. Replace capacitor ✽

4. Test winding resistance, replace

field winding if necessary ✽

1. Replace capacitor ✽

2. Adjust engine speed ✽

1. Test diodes, replace if necessary ✽

2. Adjust engine speed ✽

3. Reduce the applied load

1. Refer to engine manual

2. Referring to the wiring diagram,

clean and reconnect all wiring ✽

3. Remove all loads, then apply each

one individually to determine which
one is causing erratic function

1. Tighten all mountings

2. Test winding resistance, replace

field winding if necessary ✽

Test load devices for shorts. Replace
defective load device.

3. Replace bearing

✽ These diagnostic and repair procedures should be performed by an authorized service center.
