A bridge rectifier is composed of diodes. There are two ways to test a diode.
A. Through a Diode Test
First, make sure to disconnect the white wires and black wires from the bridge rectifier.
Then, You need to have your multi-tester dial set in Diode Test Mode. (dial setting no. 14)



B. For through Resistance Check,
You need to have your multi-tester dial set in Ohmmeter. (dial setting no. 12)

Then, check the resistance of each adjacent terminals. (top & right/ top & left/ bottom & right/ bottom & left)
You should get a resistance reading of around 97 ohms or as long as all resistance readings are approximately the same, the rectifier is good.
