Checking diodes

Checking exciter diodes

  1. Insert the probes of an ohmmeter as illustrated in the diagram.

NOTE The readings at the three exciter diode terminals should show infinite resistance (the current does not flow). Reversing the position of the instrument probes should give the diode resistance reading (the current does flow).

Checking positive diodes

  1. Turn the diode plate. Insert the probes of an ohmmeter as illustrated in the diagram.

NOTE The readings at the three positive diode terminals should show infinite resistance (the current does not flow). Reversing the position of the instrument probes will give the diode resistance reading (the current does flow).

Checking negative diodes

  1. Insert the probes of an ohmmeter as illustrated in the diagram.

NOTE The readings at the three positive diode terminals show show infinite resistance (the current does not flow). Reversing the position of the instrument probes should give the diode resistance value (the current does flow).

Dismantling

  1. Proceed as shown in the diagram in order to undo the nut fixing the pulley and then remove the latter.
