MANUAL ANTENNAS
TESTING
Antenna performance may be tested by substitut-
ing a known good antenna. It is also possible to
check short or open circuits with an ohmmeter or
continuity light once the antenna cable is discon-
nected from the radio as follows:
(1) Continuity should be present between the an-
tenna mast and radio end pin of antenna cable plug
(Fig. 8 and 9).
(2) No continuity should be observed or a very
high resistance of several megohms between the
ground shell of the connector and radio end pin.
(3) Continuity should be observed between the
ground shell of the connector and the mounting hard-
ware on the vehicle fender.
REMOVAL
AA, AC and AY bodies have a short cable that
plugs into the panel harness cable.
To remove antenna, the radio must be removed
first. See radio removal. Except AA and AC bodies.
(1) Unplug antenna lead from radio receiver.
(2) Remove antenna mast by unscrewing mast
from antenna body (Fig. 10).
(3) Remove cap nut with Antenna Nut Wrench
C-4816 (Fig. 11).
(4) Remove antenna adapter and gasket (Fig. 12).
(5) Unfasten three push pins from the rear of the
plastic inner fender shield and bend the shield away
to gain access to the antenna body.
(6) From under fender remove antenna lead and
body assembly (Fig. 12).

INSTALLATION
(1) Install antenna body and cable from under-
neath fender (Fig. 12).
(2) Install gasket, adapter, and cap nut. Tighten
cap nut to 14 N
Im (125 in. lbs.) with Antenna Nut
Wrench C-4816.
(3) Install antenna mast into antenna body until
sleeve bottoms on antenna body (Fig. 11).
(4) Route cable to radio if necessary.
BENCH TEST FOR ANTENNA MALFUNCTION
It is also possible to check short or open circuits
with an ohmmeter or continuity light once the an-
tenna has been removed from the vehicle.
(1) Continuity should be present between the tip of
the mast and radio end pin (Fig. 13 and 14).
(2) No continuity should be observed or a very high
resistance of several megohms between the ground
shell of the connector and radio end pin.
(3) Continuity should be observed between the ground
shell of the connector and the mounting hardware.
Wiggle cable over its entire length to reveal inter-
mittent short or open circuits during step 1, 2 and 3.
POWER ANTENNA
OPERATION
The power operated radio antenna (Fig. 15) is a
telescoping type antenna, extended and retracted by a
reversible electric motor.
The Automatic Power Antenna is controlled by a
combination of an external relay and limit switches
built into the antenna motor housing. The antenna is
actuated when radio is switched ON and the ignition
switch in ON or ACCESSORY position. The antenna
mast should extend. When the ignition switch or radio
is turned OFF the antenna mast should fully retract
and declutch.
Many antenna problems may be avoided by frequent
cleaning of the antenna mast telescoping sections. Clean
the antenna mast sections with a clean soft cloth.
Before an antenna is removed, the antenna perfor-
mance should be tested to decide if it is a reception
problem or an operational problem.
Whenever an operational malfunction occurs, first
verify that the radio antenna wire harness is properly
connected. Check all connectors before starting normal
diagnosis and repair procedures. Refer to Power An-
tenna Electrical Diagnosis Chart (Fig. 16).
