2.Alternator

(1)Diodes

(a)Test the resistance between the diode
and heat sink. First touch the positive
(+) prod of an ohmmeter to the diode,
then the negative (-) prod. If the
resistance is infinite in both cases, the
diode is open. If it is nearly zero in both
cases, the diode is shorted. Do the same
step for the remainder of the diodes. If
any diode is open or shorted, replace the
rectifier.

(2)Field coil

(a)Test for continuity between the slip rings
as shown in the illustration. No continuity
shows there is an open circuit in the field
coil. Replace the field coil.
(b)Test for continuity between the slip
ring and shaft(or core)as shown in the
illustration. Any continuity shows there
is a grounded circuit in the field coil.
Replace the field coil.

(3)Stator core

(a)Test for continuity between the leads as
shown in the illustration. No continuity
shows there is an open circuit in the
stator core. Replace the stator core.
(b)Test for no continuity between each lead
and stator core as shown in the illustration.
Any continuity shows there is a grounded
circuit in the stator core. Replace the stator
core.
