k. Solder R106, red/orange, black, and violet
wires to batteries. (See figure 5-9.)
m. Slide power supply into oscillator chassis and
fasten with screws removed in steps b and c.
n. Tighten screws loosened in step d.
p. Check voltage and polarity between floating
ground and bottom terminals
on batteries BT101 and
BT104. (See figure 5-9.
) Terminal on BT101 (violet
wires) must be negative and terminal
on BT104 (red/
orange wire) must bepositive with respect to floating
ground (black wire
on bottom terminals of BT102 and
BT103). Measured voltage at either terminal
will be
approximately 13 volts. If polarity
is reversed at
either terminal
or measured voltage is low (usually
less than 1 volt), batteries have not been properly
installed.
g. When conditions of previous steps have been
satisfied, turn oscillator
on and measure maximum
oscillator output voltage.
r. If maximum oscillator output voltage into an
open circuit is less than 5.0 V rms, turn oscillator
OFF and recharge batteries by following the procedure
in paragraph 3-16.
s. Replace top, bottom and side covers.
