1. Operate the alternator at minimum speed.
2. Close switch 1. Check that the lamp lights.
3. Set the load resistor to its maximum resistance
(minimum current).
4. Close switch 2.
5. Increase the alternator speed to a constant 5,000
-1
min .
6. Adjust the load resistor for maximum current output.
7. Allow the alternator to run for 15 minutes. Output
should increase as alternator temperature increases.
8. Once again, adjust the load resistor for maximum
current output.
The maximum current output must equal the
specified value. If it does not, the alternator must be
rechecked.
Alternator output:
50 amp/27 volt/5,000min
