now grounded.
Since the DN Switch at the
Antenna is now making contact to the WNT
wire, the voltage to the motor has reversed
polarity. It runs in the opposite direction and
drives the antenna down. At the end of the
travel, the DN Switch opens the circuit. Both
sets of switches are now in the positions
shown in the schematic with the Radio off
and the Antenna down.
The Antenna
is connected to the Radio by a
coaxial cable.
CIRCUIT OPERATION
When the Radio is turned on, voltage is ap-
plied from the PNK wire to the Antenna Re-
lay coil. The Antenna Relay contacts close,
and battery voltage is supplied to the
DK
GRN wire and then to the Antenna Motor.
The other motor terminal is grounded
through the UP Switch, the GRY wire, and
