NOTE: To seat new brushes atter installing them in their
holders, slip a strip of # 5O0 or # 600 sandpaper, with
the grit side up, over the commutator and smoothly ro-
tate the armature, The contact surface of the brushes
will be sanded to the same contour as the commutator.

O brush holders. lf there is continuitv, replace the
brush holder assembly.

Place the armature on an armature tester. Hold a
hacksaw blade on the armature core. lf the blade is
attracted to the core or vibrates while the core is
turned, the armature is shorted. Beplace the arma-
ture.

Performance Test
NOTE: Before starting the following checks, disconnectthe wire from terminal M, and make a connection asdescribed below using as heavy a wire as possible (prefer
ably equivalent to the wire used for the car).
Pull-in Coil Test:
Connect the battery as shown. If the starter pinion pops
out, it is working properly.
CAUTION: Do not leave the battery connectsd Jor morethan 1O seconds.
Hold-in Coil Test:
Disconnect the battery from the M terminal. lf the pin-
ion does not retract, the hold-in coil is working properly.
CAUTION: Do not leave the battery connected for more
than 10 seconds.
J
Retracting Test:
Disconnect the battery negative cable. lf the pinion
retracts immediately, it is working properly.
CAUTION: Do not leave the battery connected fol more
than 1O seconds.
Starter No]oad Test:
1. Clamp the starter firmly in a vise.
2. Connect the starter to the battery as shown, andconfirm that the motor starts and keeps rotating.
3 lf the electric current and motor soeed meet thespecifications when the battery voltage is at 1 1.5 V,the starter is working properly.
Sp€cifications: 9O A or less (Electric currentl,
