J SERIES, WSM
Regulating Voltage
1. Make the connections as shown in the figure, and turn on switch
SW1.
2. Increase the alternator speed to 83.3
3. Turn on switch SW2. Adjust load resistance R so that the
ammeter shows 10 A.
4. Check that the voltage reading on the voltmeter is within the
factory specifications.
Regulating voltage Factory spec.
No-load Characteristics
1. Make the connection as shown in the figure, and turn on switch
SW1.
2. Increase the alternator speed so that the pointer of the ammeter
swings to the plus side.
3. Turn on switch SW1 to decrease the speed, and read the speed
at witch the voltage is equal to the factory specifications.
4. The speed must be below the factory specifications.
No-load characteristics Factory spec.
Output Characteristics
1. Make the connection as shown in the figure, and turn on switch
SW1 and SW2.
2. Increase the alternator speed while adjusting the load resistance
so that the voltage complies with the factory specifications.
3. Read the speed at which the current is equal to the factory
specifications.
4. The speed must be below the factory specifications.
5. Decrease the speed so that the current approaches zero, the turn
off switches SW1 and SW2.
