at least 2 minutes before deenergizing the motor. Overheating will damage the
motor.
(1 )
Connect the starter assembly, see figure 4-33.
(2)
Use power supply to obtain 20 V dc on the voltmeter.
(3) Using RPM gage and ammeter, check starter motor speed. At a minimum current draw of 95 amperes rpm
should be at 5500 Motor speed at the maximum current draw of 120 amperes should be 7500 rpm
(4)
Connect the starter motor See figure 4-34.
Figure 4-33. No Load Test Circuit
Figure 4-34. Circuit For Checking Pinion Clearance
Do not touch exposed electrical connection when a source of power such as
utility power or another generator set is connected to the load terminals. Death or
injury may result from failure to observe this warning.
(5)
Momentarily flash a jumper lead between terminals M and G. The dove will shift Into cranking position and
remain so until the battery Is disconnected.
(6)
See Figure 4-35. Push on drive to eliminate slack.
(7)
