It is not an exhaustive “how to” for all types of problems. Procedures that require in depth knowledge or skills should be referred to the Baldor Generator Service Department by calling (920) 236−4200.

Table 5-1 General Troubleshooting Guide

Problem

Possible Cause

Remedy

 

 

 

Engine cranks but will not start

No fuel.

Check that fuel valves are ON. Check fuel level in fuel tank.

 

Low Oil Level

Low Oil Pressure Sutdown activated. Replensih oil to full.

 

Restricted air flow.

Check/replace air filter.

 

No spark.

Check/replace spark plug(s).

 

No engine speed during crank

Check that engine switch is in Start position.

 

The magnetic pickup must be correctly adjusted and operating.

 

 

 

Engine will not crank (electric start)

Dead battery.

Remove battery and trickle charge or replace with new battery.

 

 

Never Jump Start.

 

Emergency Stop LED is ON

Reset controller after an Emergency Stop.

 

 

 

Engine starts but will not run smoothly

Fuel or ignition problem

Refer to engine manual.

 

 

 

Engine overheats

Excessive load

Remove one or more electrical loads.

 

Debris or dirt buildup on engine

Remove debris. Clean engine surfaces to allow cooling.

 

 

 

No output voltage

Ciruit Breaker tripped or failed.

Reset circuit breaker or replace if required.

 

Internal failure of Alternator

Return to factory for repair.

Output voltage varies

Irregular speed (fixed speed mode)

 

Fluctuating speed (fixed speed mode)

Check engine for malfunction or load for fluctuation

Stabilize load. The addition of a lamp load (resistance load) may compensate partially for load changes caused by intermittent motor operation. Do not overload.

Loose terminal or load connections

Verify all connections and terminal tighness.

Low output voltage

Low engine speed

 

Excessive load

 

High resistance connections −

 

connections will be warm or hot

 

Internal failure of Alternator

 

Low power factor

Verify engine RPM.

Check engine for malfunction or system for overload. Reduce load. Verify all connections and terminal tighness.

Return to factory for repair.

Reduce inductive (motor) load. Some AC motors use about the same current regardless of load. Do not use motors of greater horsepower rating than is necessary to move the mechanical load.

High output voltage

Excessive speed (fixed speed mode)

Check engine for malfunction. Verify engine RPM.

Electrical shock when frame is touched

Static charge.

Ground generator frame at local reference ground (see Section 3).

 

Grounded armature or field coil.

Return to factory for repair

 

 

 

Mechanical noise

Internal failure of Alternator

Return to factory for repair

 

Loose or misaligned coupling

Tighten; align coupling and alternator shaft to engine shaft.
