NOTE: Before staning the tollowing checks. disconnect
the wire Jrom te.minal M, and make a connection as
described below using as heavy a wire as possible {prefer-
ably equivalent to the wire used for the car).
Pull-in Coil Tasl:
Connect the batterv as shown. It the starter pinion pops
out, it is working properly.
GAUTION: Do not leavo the battery connectod for mora
than 10 seconds.
Hold-in Coil Tost:
Disconnect the battetv from the M terminal. lf the pin-
ion does not retract, the hold-in coilis working properly.
CAUTION: Do not l6ave tho battory Gonnected for moro
than 10 soconds.

Rotracting Test:
Disconnect the battery negative cable. ll the pinion
retracts immediately, it is working properly.
NOTE: Do not leave the battery connected tor more than
1O seconds.
Startoi Noioad Test:
1, Clamp the starte. firmly in a vise.
2, Connect the starter to the battery as shown and con-
tirm that the motor starts 8nd keeps rotating.
It the electric current and motor speed meet the
sDecifications when the battery voltage is at 11 V,
the staner is working properly.
