TM 9-2320-360-34-1
6-2. 12-VOLT ALTERNATOR REPAIR (CONT)
(5)
Touch negative (-) test lead to bare metal
surface on negative rectifier (3).
NOTE
If
multimeter
does
not
indicate
infinity in step (6), positive rectifier is
defective. Replace rectifier.
(6)
Touch positive (+) test lead separately to
each of three eyelet terminals (2).
(7)
Touch positive (+) test lead to bare metal
surface on negative rectifier (3).
NOTE
If multimeter does not indicate low
resistance
in
step
(8),
positive
rectifier
is
defective.
Replace
rectifier.
(8)
Touch negative (-) test lead separately to
each of three eyelet terminals (2).
NOTE
If resistance reading in step (9) is
low, stator is grounded and requires
replacement.
(9)
Touch one test lead to bare metal surface
of stator (4) and other test lead separately
to each pair of three stator ring terminals
(5, 6, and 7).
NOTE
If resistance is not 1.0 ohm or less,
stator is defective. Replace stator.
(10)
Touch test leads to pairs of stator ring
terminals (5 and 6), (6 and 7), and (5 and
7), and read resistance across each set of
terminals.
