Bench Testing: Diodes

NOTE: Separate stator and diode assembly by unsoldering connecting wires. Use just enough heat to melt solder. Excessive heat will damage diodes.

Using DVOM, connect positive lead to positive diode plate, and negative lead to any diode terminal. Reverse test leads. Continuity should exist in only one direction. Repeat test procedure for each remaining diode. If continuity exists in both directions, or continuity does not exist in either direction, replace entire diode assembly.
