Testing the Diodes
Set V.O.M. at RX 100 ohms.
Disconnect the lead from one diode (see Figure H - 23).
Connect test leads across the disconnected diode (i.e., to the diode lead and the block common}.

The meter should either deflect to the right side of the scale or not at all.
Reverse polarity on the diode test leads. You should get the opposite readings from the previous step.
If the readings are the same for both steps, the diode is bad and needs to be replaced.
Reconnect the diode lead.
Repeat the previous steps for the other diode.
Note:
It
is recommended to replace the diodes as a set.
