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 figure.
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 11 V/90 A or less
Rotating speed
-
MT vehicles 2,800 rpm or more
-
AT vehicles 2,400 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):
-
MT vehicles
Voltage / Load 7.5 V / 8.73 N.m 0.89 kgf-m, 6.4 ft-lb)
Current / Speed 300 A / 890 rpm or more
-
AT vehicles
Voltage/Load 7.7 V/ 16.00 N.m 1.63 kgf-m, 11.8 ft-lb.
Current/Speed 400 A max. / 740 rpm or more
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):
-
MT vehicles Voltage / Load 4 V / 780 A or less
Torque 15.7 N.m 1.60 kgf-m, 11.6 ft-lb. or more
-
AT vehicles
Voltage / Current 3.5 V / 940 A or less
Torque 28.9 N.m 2.95 kgf-m, 21.3 ft-lb. or more
