Faulty Rectifier #1

Removed the rectifier and loom from the car. With my multimeter I used the diode test function to check out the rectifier. 

To check the rectifier I completed the following:

With the meter in diode test, first tested the +ve diodes. I put the black test lead on the black & red cable and then with the red test lead touched each of the black wires in turn. Next I swapped to the red test lead on to the black & red cable and then with the black test lead touched the black wires in turn.  In either of the two tests the results should be similar with 3 beeps in a row on one of the two tests. 

Next I completed the same test on the black & white cable and black wires. With mine I found that there were no beeps so all of the diodes are open circuit. 

I have ordered a second hand rectifier from eBay and will check with this method prior to install.
