Problems And Solutions - Baldor TS25 Installation & Operating Manual

Problems and Solutions

Some of the more common problems are listed in Table 5-1. This information is intended to be a
check or verification that simple causes can be located and fixed. It is not an exhaustive "how to"
for all types of problems. Procedures that require in depth knowledge or skills (like flashing the
field) should be referred to the Baldor Generator Service Department by calling (920) 236−4200.

Remedy
Check that fuel valves are ON. Check fuel level in fuel tank.
Check/replace air filter.
Check/replace spark plug(s). Check that engine switch is in Start
position.
Remove battery and trickle charge or replace with new battery.
Never Jump Start.
Refer to engine manual.
Remove one or more electrical loads.
Remove debris. Clean engine surfaces to allow cooling.
Replenish coolant
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.
Verify all connections are proper and check tighness torque of
terminals.
Replace worn bearing
Measure the voltage across the voltage meter with an accurate
voltmeter to verify.
Check continuity across Breaker/Fuse. Replace if defective.
Check wiring including grounds, crimps and connection points.
Repair defects.
The generator needs to be flashed. Contact Baldor service to
perform this procedure.
