Troubleshooting Chart

Symptom
Zero output from receptacles
Low output voltage with no load
High output voltage with no load
Low output voltage under load
Erratic output voltage
Noisy operation
Engine won't start
These diagnostic and repair procedures should be performed by an authorized service center.
✽
Possible Cause(s)
1. Engine speed is too slow
2. Open or shorted wiring
3. Faulty capacitor
4. Open/shorted rotor or stator windings
5. Open rectifier
6 Vac or above 1. Engine speed is too slow
2. Open rectifier
3. Faulty capacitor
4. Open/shorted rotor or stator windings
Below 6 Vac 1. Generator head not magnetized
1. Faulty capacitor
2. Engine speed is too fast
1. Open rectifier
2. Engine speed too slow at full load
3. Excessive load applied
1. Dirty, corroded, or loose wiring
connection
2. Unbalanced load applied
1. Loose generator or engine bolt
2. Short circuit in generator field or load
3. Faulty bearing
1. No fuel.
2. Fuel switch is in closed position.
3. Engine switch is in closed position.
4. Spark plug dirty or wrong gap
Corrective Action
1. Adjust engine speed
2. Clean and reconnect all wiring
3. Replace capacitor
4. Test winding resistance, replace winding
5. Test rectifier, replace if necessary
1. Adjust engine speed
2. Test rectifier, replace if necessary
3. Replace capacitor
4. Test winding resistance, replace winding
1. Re-magnetize generator head
1. Replace capacitor
2. Adjust engine speed
1. Test rectifier, replace if necessary
2. Adjust engine speed
3. Reduce the applied load
1. Referring to the wiring diagram, clean
2. Remove all loads, then apply each one
1. Tighten all mountings
2. Test winding resistance, replace field
3. Replace bearing
1. Check fuel. Use a 50:1 mix of gas and oil.
2. Place fuel switch in open position.
3. Place engine switch in open position.
4. Clean spark plug. Adjust gap. (See page 3)
