18.
On the cockpit overhead panel, set PWR XFR
NO. 1 (33) and PWR XFR NO. 2 (34) switches
to ON.
19.
Close the ENGINE NO. 1 OIL PRESS circuit
breaker (35) on the No. 1 AC PDP.
20.
Move the pilot or copilot thrust lever (17) to the
full down position, hard against the stop.
21.
Connect a multimeter to the LVDT test box (18)
input jacks. Measure the input voltages at pins 1
and 2 and pins 6 and 7. Input voltages shall be
26.000 to 29.000 vac.
22.
Record the readings to three decimal places.
23.
Connect a muitimeter to the LVDT test box (18)
output jacks. Measure the output voltages at pins
3 and 4 and pins 8 and 9.
24.
The output voltage readings shall be within the
Max and Min range that corresponds to the input
voltage shown in the table on the following page.
For example, if the input voltage is 27.70 vac,
the output voltage should be between 1.928 and
1.920 vac.
