Check to see if your voltage is dropping, your wire size might be too long or too small, 

or your service could be weak.


Step 1  -  Go to your single phase circuit breaker panel, put a voltage meter on the 

circuit breaker that is suppling the phase converter. Next turn on the phase converter 

read the voltage and shut the phase converter off, don't leave it on. If your voltage is 

dropping below 208, this could be that the service to your build is weak, call us we 

can help. Otherwise if your voltage is not dropping much then proceed to step 2.


Step 2  -  If your voltage is not dropping below 208 volts, check your voltage inside 

the phase converter panel, put your meter label L1 and L2, turn on the phase converter, 

get your voltage reading and shut the phase converter off. If your voltage is dropping

much lower then it was in your single phase circuit breaker panel and is below 208 volts, 

then your wire is too long, too small, or could have a bad connection. If this is not the case 

proceed to step 3.


Step 3  -  There is a two pole contactor, usually located right next to the black round start 

capacitors (click here for a picture) take the two Phillip head screws out and pull the cover 

off, turn on the converter for a second and see if the two pole contactor is pulling in. Larger 

phase converters will have a three pole contactor, If it is not pulling in, please call our tech 

support team, if it is pulling in, proceed to step 4. 


Step 4  -  If you reach this point, every thing with the phase converter panel and your voltage 

is good. we need to check your connection inside the idler/generator. different size idler or 

generators have different wire configurations.  The wire configurations is on the name plate 

of the motor, follow the configuration marked low voltage.  Make sure your connections are 

secure.
