STARTING MOTOR TEST - CONTINUED
Pull-in Winding Test
1.
Refer to illustration in order to make connections to solenoid. Disconnect all other leads to solenoid.
2.
Close switch. Observe reading on multimeter. Use battery load tester to adjust battery voltage until voltage is 20V.
N OT E
A high reading indicates a shorted winding. A low reading indicates excessive resistance. To avoid excessive
heat, do not leave switch closed for more than 10 seconds at a time. Current will decrease as heat increases.
3.
Observe reading on clamp-on ammeter. 9.0 to 11.5
amperes should be observed.
4.
Pull-in winding can also be checked by measuring
resistance. Disconnect batteries. Select "200 Ω" range
on multimeter. Connect one of the leads of multimeter
to "S" terminal and connect other lead to "Mtr" termi-
nal. 0.43 to 0.56 Ω should be observed:
24V
0.43 to 0.56 Ohms
32V
1.20 to 1.43 Ohms
5.
Replace starter (WP 0051 00) if any of the above read-
ings are incorrect.
