6D3 – 12 CHARGING SYSTEM
2. Check for continuity across one of the stator coils and
stator core. If a continuity exists, replace the coil.
DIODE
1. Check for continuity across the terminal (example:
across BAT and U). If a continuity exists, the diode is
in satisfactory condition. If no continuity exists the
diode is defective.
2. Make a test with the polarities reversed. If no
continuity exists, the diode is in satisfactory condition.
If a continuity exists at any point, the diode is defective
and should be replaced.
Auxiliary diodes are not provided with the terminal and
continuity test should be made across the terminals of
the conventional diodes.
