(2) Negative Rectifier Test
Check for continuity between negative rectifier and stator
coil lead connection terminal. If there is continuity in both
directions, diode is shorted, and rectifier assembly must
be replaced.
(3) Diode Trio Test
Check three diodes for continuity by connecting an amme-
ter to both ends of each diode. If there is no continuity
in both directions, diode is faulty and heatsink assembly
