4.Disconnect Wire 2 from the Voltage Regulator (VR) and connect one meter test lead to that wire. Disconnect Wire 6 from the Voltage Regulator and connect the other meter test lead to that wire. See Figure 7-4. Start the generator and measure the AC voltage. It should be above 60 volts. Record the results and stop the generator.

5.Re-connect Wire 2 and Wire 6 to the Voltage Regulator.

6.Disconnect Wire 11S from the Voltage Regulator (VR) and connect one meter test lead to that wire. Disconnect Wire 22S from the Voltage Regulator and connect the other meter test lead to that wire. See Figure 7-5. Start the generator and mea- sure the AC voltage. It should be above 60 volts. Record the results and stop the generator.
