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 figure.

1. No-load test

   Adjust the variable resistance with the switch on until the voltage is 11 V, and read the value displayed on the ammeter to measure rotating speed. Compare these values with the standard.

   No-load test (standard): 

   Voltage/Current 

   Max. 11 V/90 A or less 

   Rotating speed 

   2.5 L model 

   1, 900 RPM or more 

   3.6 L model 

   1, 550 RPM or more 

2. Load test

   Apply the specified braking torque to starter. The condition is normal if the current draw and rotating speed are within standard.

   Load test (standard): 

   Voltage/Load 

   2.5 L model 

   8 V/11.1 N.m (1.1 kgf-m, 8.2 ft-lb) or more 

   3.6 L model 

   8 V/12.8 N.m (1.3 kgf-m, 9.4 ft-lb) or more 

   Current/Rotating speed 

   2.5 L model 

   370 A/910 RPM or more 

   3.6 L model 

   370 A/800 RPM or more 

3. Lock test

With the starter stalled, or not rotating, measure the torque developed and current draw when the voltage is adjusted to standard voltage.

Lock test (standard): 

Voltage/Current 

3 V/750 A or less 

Torque 

2.5 L model 

15.5 N.m (1.6 kgf-m, 11.4 ft-lb) or more 

3.6 L model 

19.0 N.m (1.9 kgf-m, 14.0 ft-lb) or more
