(a) Observe voltmeter (2, Fig. 2) one! turn rheostat (37) CLC.C!<W!SE to fcli!
clockwise position. Maximum voltage shoutd be at ieact 134 V AC, or
higher.
NOTE: If vo!tagc shou!d decrease when the knob is turned clockwise,

correct. Replace the complete regulator tray assembly,.
(b) Observe voltmeter and turn rheostat knob to full COUNTERCLOCKWISE
position. Minimum voltage shou!d be 108 V AC, or lower.
Observe voltmeter and adjust rheosjat to obtain 115-V AC vo!tmeti:r reading.
.
Check adiustable voltage range in manual oparcting mode.
(a) Open the generotor .controJ tray .( 14, F ig. 2)..and place the automatic-
manual switch (33) in MANUAL position.
(b) Observe voltmeter (2) and turn manual control rheostat (32) CLOCKWISE
to full clockwise position.
Maximum voltage should be at least 160 V AC.
(c)
Observe voltmeter and turn rheostat (32)
to
full COUNTERCLOCKWISE
position. Minimum voltage should be 95 V AC or less.
(d) Adjust voltage to 115 V AC, then return the atiomotic-manual switch
to AUTOMATIC position.
Position load bank switches, etc.,
to apply a light ioad to the generator.
Place the load contactor "on-off" switch (20, Fig. 2) in the top, spring loaded,
CLOSE position. Hold in this position momentarily. The indicatiag light (22)
should glow GREEN and an amperage value should appear on tfle AC ammeter
