Generator Bench Check
2.
Make connections as shown in Figure above. Be sure carbon pile is turned off.
Ground polarity of generator and
must be same. Battery must be fully
charged. Use a
30-500 ohm
resistor between battery and "L" terminal of
generator.
3.
Slowly increase generator speed and observe voltage using J 39200.
Important
•
must be fully charged when making this test.
•
The engine must be run at
2500 RPM
and at ambient temperature.
