SIMPLE TROUBLESHOOTING
Listed below are the more simple solutions to some of the more common problems that are
reported to the Customer Services Department at Baldor Generators of Oshkosh. 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.
THE CAPACITOR USED IN THIS GENERATOR SET CAN STORE AND
DISCHARGE A HIGH VOLTAGE CHARGE. BEFORE WORKING WITH, OR
AROUND THE CAPACITOR YOU SHOULD DISCHARGE IT BY SHORTING
THE CAPACITOR'S LEADS TOGETHER WITH A SCREWDRIVER THAT HAS
AN INSULATED HANDLE YOU CAN HOLD ON TO.
NO OUTPUT
Possible Problems:
1.
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.
2
. 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.
3
. Bad capacitor . If the capacitor in your generator goes bad, your generator set will produce
no power. To check the capacitor, usually located on the tail end of the generator) you should
first discharge it as previously explained and then remove the wires that connect to it. Then
put a 12 VDC charge into it by connecting the leads of a 12 VDC battery across the capacitor's
terminals for one second. Then allow the capacitor to sit undisturbed and disconnected from
everything for 30 minutes. After 30 minutes measure the DC voltage potential across the
capacitor. If the capacitor is good, it will still have approximately 12 VDC charge in it. If the
capacitor is bad, the voltage potential across the capacitor will be substantially less.
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:
