3-10. Test Facilities
A dc power source of +27.5 volts 0.5 is re-
quired to furnish the operating voltages. To
deck the 115-volt, 400-Hz circuitry in the main-
tenance kit, an alternating current (aC) power
source of 115 volts 5, at 400 Hz, single phase
is required for testing, as described in the adf
test circuit tests (para 3-16c).
3-11. Fabrication of Voltage Divider and
Special Test Probes
Testing of meters in the HOMING/ADF/GYRO
indicators requires the application of low level dc
voltages to pins on J1. The low level voltages
are derived by reducing the output voltage of the
+28-volt power
