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: 
 
 Preferred 

Method 

A.   With the generator set stopped, remove the generator's end cover and locate the set  

                of three posts on the rotor plate at the tail end of the rotor (there will be a wire  
                wrapped around the center post and the left hand post). 
 
 

B.   Using a 12 VDC battery, touch the positive battery lead to the center post while  

                touching the negative battery lead to the right hand post. Allow the battery to remain  
                across these posts for 2 seconds. 
 
  

C.   Replace the end -cover and start the unit. 

 
 Alternate 

Method 

With the generator running and the end cover removed, momentarily connect a 12 VDC  

          battery across the capacitor's terminals for a fraction of a second. (Having the battery  
          across the capacitor longer than a fraction of a second may damage the windings of the  
          generator). Stop the unit after doing this and replace the end -cover. If you still have no  
          output, look for other reasons or contact the Technical Support Department at Baldor  
          Generators. 
 

BE EXTREMELY CAREFUL WHEN USING THE ALTERNATE METHOD FOR 

                                               FLASHING THE GENERATOR AS YOU WILL BE WORKING AROUND FAST, 
                                               ROTATING COMPONENTS ALONG WITH LIVE WIRES AND BARE CONNECTIONS. 
                                             

LOW VOLTAGE OUTPUT 

Possible Problems: 

1.

   Generator speed 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 specified 
      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. 
 
 
 

HIGH VOLTAGE OUTPUT 

 
Possible Problems: 
 

1.

   Generator speed too fast. 

If the generator is turning too fast the generator set will produce 

      high output voltage. Make sure the generator is turning at the speed specified on the  
      nameplate.
