INSPECTION

1. SWITCH ASSEMBLY
Using a circuit tester (set to "ohm"), check that there is continuity between terminals S and M, and between terminal S and ground.
Also check to be sure there is no continuity between terminals M and B.

Terminal/Resistance:
S - M/1 Ohms or less
S - Ground/1 Ohms or less
M - B/1 M Ohms or more






2. SWITCH ASSEMBLY OPERATION

NOTE: Perform each test in a short period of time (3 - 5 sec).

1. Suction test
Check that the pinion gear comes flying out when the harness is disconnected from terminal M and connected as shown in the figure.






2. Holding test
Check that the pinion gear remains flying out after the cable is disconnected from terminal M.






3. Returning test
With terminal S connected to the positive terminal, and terminal M and starter body connected to the battery ground terminal to suction the main contact point, check that the pinion gear returns to its original position when terminal S is disconnected.






3. 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

4. OTHER INSPECTIONS
Check that the starter does not have deformation, cracks and any other damage.
