9. Check each diode in the rectifier for conduction
(Fig. 53). Connect an ohm meter across the lead wire
and diode case. The diode is normal if its resistance is
large in one direction and small in the reverse direction.
If there is equal resistance in both directions the diode
is damaged. Replace the rectifier assembly if a diode is
damaged.
10. Check the field coil for continuity between the slip
rings (Fig. 54). If there is no continuity, replace the field
coil.
