TOOL REQUIRED:
J 39200 Digital Multimeter or equivalent
The following bench check may be used to simulate operation on a vehicle. Use the

1.
Mount generator in suitable test stand according to test stand manufacturer's
instructions. Test stand must be capable of driving generator at
6,500 RPM.
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.
