ENGINE ELECTRICAL SYSTEM
6-1
1) No-load test
With switch on, adjust the variable resistance to obtain 11 V,
take the ammeter reading and measure the starter speed.
Compare these values with the specifications.
No-load test (Standard):
Voltage/Current
11V/90A max
Rotating speed
MT 3,000 rpm min
AT 2,900 rpm min
2) Load test
Apply the specified braking torque to starter. The condition
is satisfactory if the current draw and starter speed are within
specifications.
Load test (Standard):
Vo Itage/Load
MT aV/8.S N·m (0.87 kg-m, 6.3 ft·lb)
AT aV/14 N·m (1.4 kg-m, 10 ft·lb)
Cu rrent/Speed
MT 2aOA max/9aO rpm min
AT 370A max/aaO rpm min
3) Lock test
With starter stalled, or not rotating, measure the torque
developed and current draw when the voltage is adjusted to
the specified voltage.
Lock test (Standard):
Voltage/Current
MT 4V/780A max

3) Remove both through-bolts and brush holder screws,
and detach rear bracket and brush holder.

AT 4V/980A max Fig. 11
Torque
MT 18 N·m (1.8 kg-m, 13 ft-Ib) min
AT 2S N·m (2.6 kg-m, 19 ft-Ib) min
DISASSEMBLY
1) Loosen nut which holds terminal M of switch ASSY, and
disconnect connector.
2) Remove bolts which hold switch ASSY, and remove
switch ASSY, plunger and plunger spring from starter as a
unit.
Be careful because pinion gap adjustment washer may some-
times be used on the mounting surface of switch ASSV.
