9. Check each diode in the rectifier for conduction.
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 dam­
aged. Replace the rectifier assembly if a diode is dam­
aged.
10. Check the field coil for continuity between the slip
rings. If there is no continuity, replace the field coil.
