5.Activate starter motor and note readings of meter and tachometer.Take reading after meter stabilizes (approximately 2-3 seconds).

6.A starter motor in good condition will be between the following specs:

•6500 RPM (minimum) and 35 Amps (maximum)

-OR-

•5000 RPM (minimum) and 20 Amps (maximum)

-OR-

•7000 RPM (minimum) and 24 Amps (maximum)

If starter motor is not within specifications, it must be replaced.

Test Solenoid

Some engines or equipment have a solenoid mounted to the starter motor or to the frame of the equipment.

The solenoid is normally open. When the key switch is turned to the START position, the solenoid closes, allowing battery current to flow to the starter motor and crank the engine.

The solenoid may be tested while mounted on the engine or equipment. A jumper test lead (A, Figure 39) is required for this test.

1.Key switch must be in OFF position.

2.Remove positive (+) battery cable from battery and from stud terminal on solenoid.

3.Disconnect wire from tab terminal on solenoid.

4.Insert RED test lead into the V Ω receptacle in the meter and insert BLACK test lead into COM receptacle in the meter.

5.Set meter to Diode position.

6.Attach one meter test lead to each stud terminal (B,C) on solenoid.

Figure 39

7.Attach one end of jumper lead to positive (+) battery terminal (E).

8.Touch other end of jumper lead to tab terminal (D) on solenoid. A click should be heard as the solenoid switch closes and the meter should indicate continuity. If solenoid fails this test, replace it.
