SIMPLE TROUBLESHOOTING
Listed below are the more simple solutions to some of the more common problems that are reported
to the Service Department at Baldor Generators. These troubleshooting solutions are meant to be an
aid for a person who has minimal electrical knowledge and experience. More in-depth, detailed
troubleshooting information for a person more knowledgeable and experienced in electricity can be
obtained by contacting the Technical Service Department at Baldor Generators by calling (920) 236-
4200.
BEFORE BEGINNING TO TROUBLESHOOT THE GENERATOR SET,
DISCONNECT THE SPARK PLUG (IF APPLICABLE) AND THE BATTERY
(IF APPLICABLE) AND ALLOW THE UNIT TO COOL DOWN.
EYE PROTECTION SHOULD BE WORN WHILE TROUBLESHOOTING
THIS GENERATOR SET.
NO OUTPUT
1
. Bad Voltage regulator fuse
. Check the voltage regulator fuse and replace it if necessary.
2.
The generator speed is too slow
.
If the generator is turning too slow the generator set will
produce low or no output voltage. Make sure the generator is turning at the speed on the
nameplate.
3
. Broken wires or loose connections.
Broken wires or loose connections can cause the
generator set to have low or no output voltage. Check all wiring for broken wires and
bad/loose connections.
4.
Bad circuit breaker
. If a circuit breaker opens up and will not reset, or the reset button is
not free-floating, your generator will not produce power out of all the receptacles. Check for
continuity across each circuit breaker with a continuity tester or ohmmeter (The wires must
be removed from the circuit breaker prior to checking it).
5.
Loss of residual magnetism
. Loss of residual magnetism will not allow the generator's
excitation system to build up and thus the generator set will not produce any power. To 'Flash'
the generator set, (restore residual magnetism) follow these steps:
A. Disconnect exciter winding leads F1 and F2 from the voltage regulator.
B. Start the generator set.
C. With the generator set running, apply 12VDC from a wet cell battery (Automotive type) to
the F1 and F2 exciter winding leads for 1 second.
D. Stop the generator set and reconnect the F1 and F2 leads to the voltage regulator.
