TESTING GENERATOR DIODES
The following method eliminates the need to disconnect the
diodes from the generator wiring.
1. Use a 12 Volt battery and automotive lamp (Type 5001) to
test the diodes in the generator.
2. Connect the battery and lamp as shown in Figure 3.
3. If the diodes are operating properly, the lamp illuminates
brightly when the battery polarity is correct, and goes
dim when battery polarity is reversed.
4. If there is no change in lamp brightness when polarity is
reversed, the doides must be replaced.
For testing of rotor, stator, or field
windings, consult an authorized service
center.
