TROUBLESHOOTING
Problem Possible Cause Corrective Action
Zero output from
receptacles
1. Engine speed is too slow
1. Adjust engine speed(ask repair
shop for help)
2. Open or shorted wiring 2. Clean and reconnect all wiring
3. Faulty capacitor 3. Replace capacitor
4. Open/ shorted rotor or stator
windings
4.Test wiring resistance, replace
winding if necessary
5. Open rectifier 5. Test rectifier, replace if necessary
Low output voltage
with no load
1. Engine speed is too slow
1. Adjust engine speed(ask repair
shop for help)
2. Open rectifier 2. Test rectifier, replace if necessary
3. Faulty capacitor 3. Replace capacitor
4.Open/shorted rotor or stator
windings
4.Test winding resistance, replace
winding if necessary
5. Alternator not magnetized 5. Re-magnetize the alternator
High output voltage
with no load
1. Faulty capacitor 1. Replace capacitor
2. Engine speed is too fast 2. Adjust engine speed
Low output voltage
under load
1. Open rectifier 1. Test rectifier, replace if necessary
2. Engine speed is too low at full
load
2. Adjust engine speed(ask repair
shop for help)
3. Excessive load applied 3. Reduce the applied load
Erratic output
voltage
1. Dirty, corroded, or loose wiring
connection
1. Referring to the wiring diagram,
clean and reconnect all wiring
2. Unbalanced load applied
2. Remove all loads, then apply each
one individually to determine which
one is causing erratic output.
Noisy operation
1. Loose generator or engine bolt 1. Tighten all mountings
2. Short circuit in generator field or
load
2. Test winding resistance, replace
field winding if necessary; Test load
devices for shorts. Replace
defective load device
3. Faulty bearing 3. Replace bearing
Engine won’t start
1. No fuel 1. Check fuel
2. Fuel switch is in closed position 2. Place fuel switch in open position
3.Engine switch is in closed
position
3. Place engine switch in open
position
4. Spark plug dirty or wrong gap
4. Clean spark plug. Adjust gap,
replace if necessary
5. Low cylinder compression 5. Check cylinder for leakage
