Remove Starter Motor:

It is recommended that the Starter Motor be removed from the engine when testing Starter Motor perfor- mance. Assemble starter to test bracket and clamp test bracket in vise (Figure 7-26).

Testing Starter Motor:

1.A fully charged 12 volt battery is required.

2.Connect jumper cables and clamp-on ammeter as shown in Figure 7-26.

3.With the Starter Motor activated (jump the termi- nal on the Starter Contactor to battery voltage), note the reading on the clamp-on ammeter and on the tachometer (rpm).

Note: Take the reading after the ammeter and tachometer are stabilized, approximately 2-4 seconds.

4.A starter motor in good condition will be within the following specifications:

Minimum rpm

4500

 

 

Maximum Amps
