b) If replacing the regulator does not restore proper operation, check the voltage output from the alter-
nator, as in point 2a. Checking the output voltage at 3000 rpm on the c.c. section is greater than or
equal to 25V.

STARTER MOTOR
Specification Desc./Quantity
Rated voltage 12V.
rated power 0.25 Kw.
Rotation Left.
Bench tests
TESTS TO BE PERFORMED AT THE BENCH WHEN THE STARTER MOTOR HAS TO BE OVER-
HAULED.
1) No-load test: the starter motor, under no-load, must draw a maximum of 30 Amp. with a supply voltage
of 11.5 to 12V and must rotate at rpm 11,000.
2) Load test: braking the starter motor so that it draws 60 Amp, and with a supply voltage of 10 to 10.5
V a torque 0.06 kgm must be obtained, for no lower than 4,600 rpm.
3) Pickup test: with rotor locked and a supply voltage 8 to 8.5V the current drawn must not be higher
than 160 Amp and the torque must be no lower than 0.3 kgm.
N.B.
THE VALUES SHOWN ABOVE MUST BE TAKEN WITH A CHARGED BATTERY AND AFTER THE
STARTER MOTOR HAS BEEN ROTATING FOR 30" UNDER CONDITIONS OF POINT 1.
