Common problems
15- Shutdown or unit may continue to run but will not start at the next attempt
Cause: Due to low coolant level in the radiator
Fix: Add one to two cups of coolant to the radiator. Be sure to connect the coolant recovery tank to the system, as it is an integral and required part of the cooling system. - Shutdown may be due to low fuel level
Fix: Check for a low fuel or low coolant level condition. Add coolant at the pressure cap if it is not completely full. Add coolant to the recovery tank to bring the level up to the appropriate mark. - Shutdown may be due to low coolant level in the radiator
Cause: Low coolant level in the radiator
Fix: Add one to two cups of coolant to the radiator. Be sure to connect the coolant recovery tank to the system, as it is an integral and required part of the cooling system. - Shutdown due to low fuel level
Fix: Check for a low fuel or low coolant level condition before starting the unit - Shutdown due to low coolant level
Fix: Add one to two cups of coolant to the radiator; ensure the coolant recovery tank is connected and used - Low oil pressure shutdown
Fix: Check the oil level regularly and add oil as needed; this is not a low oil level shutdown, proper oil level must be maintained for low oil pressure shutdown switch to function - Low Oil Pressure
Cause: Oil pump fault or other engine malfunction - High water temperature shutdown
Fix: Not specified in the text - High Water Temperature
Cause: Engine coolant temperature exceeds 230_F (110_C) - Generator set shuts down automatically
Fix: Identify and correct the problem before attempting to restart - Engine starts and then stops
Fix: Allow the engine to come to a complete stop before making a restart attempt; if flywheel ring gear is still rotating when starter pinion gear is engaged, damage may occur - Engine fails to start after three attempts
Fix: Contact an authorized service dealer/distributor for repair - Will not start (cranks okay)
Fix: Replenish, Check continuity, Replace fuel feed pump, Clean or replace element, Troubleshoot engine, Bleed air, Drain, flush fuel system, Check injectors, Check compression, Use proper type of fuel; consult fuel supplier, Use proper lube oil, Check valve clearance, Replace filter, Check continuity, Check relay coil continuity, Service/Engine Service Manual - Will not carry load pump
Cause: Defective injection pump or runs rough
Fix: Check injection pump, engine speed using frequency meter or tachometer. NOTE: Hz x 120/No. of rotor poles = rpm (Example: 60 x 120/4 = 1800) - Unit is noisy
Cause: Excessive vibration—engine/generator, Exhaust system leak, Broken or damaged vibro mounts, Loose or vibrating sheet metal/housing, Inadequate compartment clearances, Exhaust piping or air inlets/outlets not securely installed, No compartment sound insulation
Fix: Check and replace as necessary, Check and replace as necessary, Retighten screws, Check clearances, Inspect for loose parts, Install fireproof insulation, Check rotor, crankshaft, bearing, etc. (Disassembly of engine and/or generator may be required)
