Checking the rectifier bridge

 

 
The rectifier bridge is made up of button diodes on aluminium sheets which act as dissipaters. 
To  achieve  different  current  capacities,  the  bridge  is  made  up  of  a  variable  number  of  diodes,  positioned  in 
parallel on the same plate. 
 
To test operation of the Rectifier Bridge, remove it from the charger. 
 
 
 
 
 
 
 
 
 
 
 
To check the condition of these diodes,  
use a 

Digital tester in “Check-Diode”

 mode : 

 
 
 
 
 
 
 
1)  Make sure that a 

diode voltage 

(0,4V÷0,8V) is present by pointing the 

positive test prod on the phases

 

input from transformer and the 

negative test prod on the positive output pole
