6. INSPECT EXPOSED BRUS H L E NG T H
Using vernier calipers, measure the exposed brush length.
Standard exposed length:
10.5 mm (0.413 in.)
Minimum exposed length:
1.5 mm (0.059 in.)
If the exposed length is less than the minimum, replace the
brushes.
7. IF NECESSARY, REPLACE BRUS HE S
(a) Unsolder and remove the brush and spring.
(b) Run the wire of a new brush through the hole in the brush
holder, and insert the spring and brush into the brush
holder.
(c) Solder the brush wire to the brush holder at specified ex-
posed length.
Exposed length:
10.5 mm (0.413 in.)
(d) Check that the brush moves smoothly in the brush holder.
(e) Cut off the excess wire.
(f) Apply insulation paint to the soldered area.
8. INSPECT POSITIVE RECTIFIER
(a) Using an ohmmeter, connect one tester probe to the posi-
tive (+) terminal and the other to each rectifier terminal.
(b) Reverse the polarity of the tester probes and repeat step
(a).
(c) Check that one shows continuity and the other shows no
continuity.
If continuity is not as specified, replace the rectifier holder.
9. INSPECT NEGATIVE RECTIFIER
(a) Using an ohmmeter, connect one tester probe to each
negative (--) terminal and the other to each rectifier termi-
nal.
(b) Reverse the polarity of the tester probes and repeat step
(a).
(c) Check that one shows continuity and the other shows no
continuity.
If continuity is not as specified, replace the rectifier holder.
