Common problems

The battery is very warm to the touch.
Fix: Reduce the rate of charging by a signiﬁcant amount. Complete the charging at the reduced rate.
The battery emits smoke or a dense vapor (gas).
Fix: Reduce the rate of charging by a signiﬁcant amount. Complete the charging at the reduced rate.
Overheating of the generator too quickly
Fix: Do not heat the generator too quickly. Try to limit the rise in temperature of the insulation and windings to 11.11° C (20° F) per hour.
Localized overheating
Cause: Radiant ovens sometimes cause localized overheating.
Internal heating required
Cause: Generators are in damp environments and go for long periods of time without operation. Generators operate regularly in an environment with moisture laden air.
Fix: The electric space heaters should be installed as part of the generator.
Insulation resistance test failure
Fix: Heat the generator to approximately 75° C (167° F). Never exceed 75° C (167° F) until the insulation tester tests correctly for insulation resistance (at least 4 hours).
Insulation resistance below normal
Fix: Cleaning is advisable if heavy accumulations of dirt can be seen or if heavy accumulations of dust can be seen. If excess dirt is the cause of a restriction in the ventilation, cleaning is also advisable.
Insulation breakdown
Fix: An insulation breakdown requires repair. A high pressure wash is normally an effective way to clean windings. This includes windings that have been exposed to flooding or windings that have been contaminated by salt.
Dirt accumulation
Fix: Cleaning may be required at the point of installation. A vacuum cleaner should be used to pick up dry dirt, dust, and carbon. After most of the dust has been removed, a small brush may be attached to the vacuum hose in order to loosen dirt that is more firmly attached to the surface. Compressed air may be used to remove the remaining dust and dirt.
Circulating current needed
Fix: Drying can be accomplished by circulating low voltage current through the windings. Since the voltage is low, the breakdown of the insulation will not occur as the breakdown might have occurred with normal operation and wet insulation.
A strong odor of acid is present.
Fix: Reduce the rate of charging by a signiﬁcant amount. Complete the charging at the reduced rate.

Very Low Coolant Level 111-11
Very High Intake Manifold Air Temperature 105-11

Insulation - Test (Recommended Procedure for A Periodic Insulation Test) diagnostic

⚠ The high voltage that is produced by an operating generator set can cause severe injury or death.

⚠ The megohmmeter is applying a high voltage to the circuit. Do not touch the instrument leads without first discharging them.

Tools: 142-5055 Insulation Testing Gp, 9U-6003 Insulation Testing Gp

Take the generator out of service.
Visually inspect the generator for moisture. If moisture exists, dry the unit first.
Discharge the capacitance of the windings.
Isolate the stator windings by disconnecting all other leads and cables from the generator terminals.
Connect the insulation tester's RED lead to ground.
Connect the insulation tester's BLACK lead to the wye point of the generator's windings.
Set the voltage to 500 Volts for units of 600 volts or less; 1000 Volts for units more than 600 volts.
Apply voltage and observe readings at 30 seconds and 60 seconds. Record the 60 second reading, temperature and humidity.

Severe Service Application - Check diagnostic

Severe service is an application of an engine that exceeds current published standards for that engine.
Caterpillar maintains standards for performance, fuel quality, altitude range, maintenance intervals, oil selection, coolant selection, environmental qualities, and installation.
Engines that operate under severe conditions may need more frequent maintenance intervals.
Environmental factors include ambient temperatures, air quality, buildup, and altitude.
Improper operating procedures include extended low idle, frequent hot shutdowns, excessive loads, excessive speeds, and operating outside intended application.
Improper maintenance procedures include extending maintenance intervals and failure to use recommended fuel, lubricants, and coolant/antifreeze.

Triggering the snapshot with the Cruise Control Set/Resume Switch diagnostic

Toggle the switch quickly from the OFF position (1) to the SET position (2).
Toggle the switch quickly from the SET position (2) to the RESUME position (3).
Toggle the switch quickly from the RESUME position (3) back to the OFF position (1).
The switch must be toggled within a one second time period to take a snapshot. The procedure can also be performed in reverse order.
