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. 

 

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).
