(d) Shut down generator and turn electrical power OFF and tag (TM 55-1905-223-10). Remove the

separate 12 volt battery and reconnect all leads to the voltage regulator and externaconnections

that were removed for test purposes.

(4) With the generator set shut down and cool, and electrical power OFF, check the rectifier

semiconductors. The rectifier assembly (Figure 3-6) is split into two plates, positive and negative, and

the main rotor is connected across these plates. The positive plate has three positive semiconductors,

and the negative plate has three negative semiconductors.

CAUTION

Ensure that the correct polarity of the semiconductors is fitted to

each respective plate.
