SLIP RINGS
If the slip rings are dirty, polish them with #400 sandpaper and
wipe them using a clean, dry cloth.
Then, measure the slip ring O.D. using vernier calipers. If it is less
than the service limit, replace the slip rings with new ones.

CARBON BRUSHES
Measure the length of the carbon brushes as shown. If the mea-
surement is less than the service limit, replace the carbon brushes
with new ones.

RECTIFIER
Measure the voltage among the terminal 1 and the other termi-
nals (P1, P2, P3 and P4). Put the tester lead on the terminal 1
and the other lead to P1, P2, P3 and P4 terminals. Observe the
reading and then switch the leads. Perform other side tests among
the terminal 2 and the other terminals (P1, P2, P3 and P4), as
described below. If the voltage measured is excessively out of
specification, replace the rectifier.

IC REGULATOR
Measure the continuity between terminal "F" and terminal "B".
There should be continuity in only one direction.
F : Rotor coil terminal
B : Battery terminal
