TABLE 4. TROUBLESHOOTING (CONT.)

Some genset service procedures present hazards that can result in severe per-

sonal injury or death. Only qualified service personnel with knowledge of fuels, electricity, and

machinery hazards should perform genset service. See Safety Precautions.

WARNING

STARTING BATTERIES RUN DOWN

(Marginal battery, battery connections, or charging system; or parasitic loads)

Corrective Action:

1. Clean and tighten the positive (+) and negative (−) battery cable connections at the battery, vehicle

frame and genset (Page 17).

2. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations.

ENGINE CRANKS BUT DOES NOT START

(Fuel delivery, glow plugs or engine are marginal)

Corrective Action:

1. Check fuel level. (Note: The genset fuel pickup is probably higher than the vehicle engine pickup.)

2. Prime the engine fuel system by holding the control switch down in its Stop position for at least 1 min-

ute.

3. Check the engine air filter and remove any blockage (Page 17).

4. Replace Fuse F3 (glow plugs) if blown (Page 7).

STARTER ENGAGES-DISENGAGES

(Cranking voltage dips below 6 volts—low battery charge, poor connections, long cables)

Corrective Action:

1. Have the vehicle propulsion engine running while trying to start the genset—the battery charging

alternator may be able to maintain starting voltage high enough to get the genset started.

2. Clean and tighten the positive (+) and negative (−) battery cable connections at the battery, vehicle

frame and genset (Page 17).

3. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations.

4. Increase battery cable size or run parallel cables.

NO POWER—GENSET RUNNING, RUN LIGHT ON

(Line circuit breaker OFF or tripped or faulty wiring)

Corrective Action: Reset or turn “On” the line circuit breaker on the genset operator’s console.

GENSET HUNTS UNDER FULL LOAD

(Fuel delivery marginal, governor misadjusted)

Corrective Action: Prime the engine fuel system by holding the control switch down in its Stop posi-

tion for at least 1 minute.
