7. PERFORMANCE TEST
The starter should be submitted to performance
tests whenever it has been overhauled, to assure
its satisfactory performance when installed on the
engine.
Three performance tests, no-load test, load test,
and lock test, are presented here; however, if the
load test and lock test cannot be performed, carry
out at least the no-load test.
For these performance tests, use the circuit shown
in the figure.

1) No-load test
With switch on, adjust the variable resistance for
the voltage to obtain 11 V, read the ammeter and
measure the starter speed. Compare these values
with the specifications.
No-load test (Standard):
Voltage / Current
MT model
11 V / 95 A or less
AT model
11 V / 90 A or less
Rotating speed
MT model
2,500 rpm or more
AT model
2,000 rpm or more
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):
Voltage / Load
MT model
!
7.5 V / 8.84 N m (0.90 kgf-m, 6.5 ft-lb)
AT model
!
7.7 V / 16.7 N m (1.70 kgf-m, 12.3 ft-lb)

Current / Speed
MT model

AT model

3) Lock test
With the starter stalled, or not rotating, measure the
torque developed and current draw when the volt-
age is adjusted to the specified voltage.
Lock test (Standard):
Voltage / Current
MT model
4 V / 680 A or less
AT model
3.5 V / 960 A or less
