REPLACING THE BRIDGE RECTIFIER 

 
The rectifier converts 110 volt line voltage to the approximately 12 volts DC that the 
pump motor operates on. There can be two symptoms caused by a bad rectifier. First, 
when the rectifier goes bad, the pump will not run. Also, occasionally when the rectifier 
goes bad it will imbalance the commutator on the vacuum motor causing it to spark 
excessively and become noisy. If the pump motor does not run, check the current coming 
into the motor. If there is no current present, check to ensure all wire connections are 
secure and replace the bridge rectifier if necessary. 
 
The bridge rectifier is located between the pump and the motor
