CAUTION

Never let voltage on DC VOLTMETER (3) be more

than 32 volts or ampere reading on DC FIELD AND

BATTERY CHARGER AMMETER (4) be more than

15 amperes or rectifier may be damaged.

1. Turn FIELD CURRENT control (1) to the right until DC LOAD AND STARTER

AMMETER (2) reads 100 amperes and DC VOLTMETER (3) reads 68 volts.

DC FIELD AND BATTERY CHARGER AMMETER (4) should read 9 to 11

amperes.

2. Turn AC AMMETER PHASE selector (5) through A, B, and C positions. AC

AMMETER should read about the same in all three positions.

3. Turn AC VOLTMETER selector (6) through T1-T2, T1-T3, and T2-T3 posi-

tions. AC VOLTMETER (7) should read about the same in all three positions.

4. If DC FIELD AND BATTERY AMMETER (4) reads less than 9 amperes or

more than 12 amperes, get a new regulator.
