3. INSPECT BRUSHES
Using a scale, measure the exposed brush length.
Standard exposed length:
9.5 - - 11.5 mm (0.374 - - 0.453 in.)
Minimum exposed length:

INSPECT RECTIFIER (RECTIFIER HOLDER)

(a) Check the positive (+) rectifier.
(1) Using an ohmmeter, connect one tester probe to the
positive (+) terminal and the other to each rectifier
terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
shows no continuity.
If continuity is not as specified, replace the rectifier holder.
(b) Check the negative (--) rectifier.
(1) Using an ohmmeter, connect one tester probe to
each negative (--) terminal and the other to each
rectifier terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
