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

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

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.
