Rectifier Bridge Test - CS-144 Generator

Rectifier Bridge Test:

To test the rectifier bridge, connect an ohmmeter to the grounded heat sink and one of the three terminals, pressing down firmly on the flat metal clip. Observe the ohmmeter adding and reverse the lead connectors to the grounded heat sink and the same metal clip. If both readings are the same, replace the rectifier bridge. A good rectifier bridge will give one high and one low reading. Repeat this procedure between the grounded heat sink and the other two terminals, and between the insulated heat sink and each of the three terminals. This makes a total of six tests, with two readings taken for each test.

Some digital ohmmeters cannot be used to test diodes in the rectifier bridge. Consult the ohmmeter manufacturer to determine your ohmmeter capabilities.
