TABLE 4-1. TROUBLESHOOTING
Some genset service procedures present hazards that can result in severe per-
sonal injury or death. Only trained and experienced service personnel with knowledge of fuels,
electricity, and machinery hazards should perform genset service. See Safety Precautions.
WARNING
NO RESPONSE AT CONTROL SWITCH
(Faulty switch, poor or missing connections, dead battery)
Corrective Action:
1. Try the genset (local) control switch if there is no response at the remote control switch, and vice
versa.
2. Check for 12 VDC across genset battery cable terminal block. Service as necessary by cleaning and
tightening battery cable connections, recharging or replacing the battery or replacing damaged or
missing battery cables.
THE STARTER ENGAGES AND DISENGAGES
(Low cranking voltage)
Corrective Action:
1. Have the vehicle propulsion engine running while trying to start the genset. Its charging alternator
may be able to maintain a high enough battery terminal voltage to start the genset.
2. Service the battery as necessary by cleaning and tightening connections, recharging or replacing
the battery or replacing damaged battery cables.
THE STARTING BATTERIES DO NOT MAINTAIN A CHARGE
(Marginal battery, battery connections or charging system)
Corrective Action:
1. Service the battery as necessary by cleaning and tightening connections, recharging or replacing
the battery or replacing damaged battery cables.
2. Have the battery recharging system serviced.
NO AC POWER WHEN GENSET IS RUNNING
(A Circuit Breaker is OFF, tripped or malfunctioning or there are poor AC harness connections)
Corrective Action:
1. Reset or turn ON genset circuit breaker CB1.
2. Reset or turn ON any other circuit breaker in the AC power supply system.
PERSISTENT, AUDIBLE ENGINE SURGING—WITHOUT FAULT SHUTDOWN
(Fuel leaks, restrictions or air bubbles, worn slip rings/brushes, misadjusted or faulty governor,
worn generator bearing)
Corrective Action:
1. Check all fuel fittings for fuel and air leaks and tighten as necessary. Reprime.
2. Replace the fuel filter (p. 3-6).
