Chrysler Le Baron, Dodge Dynasty, Plymouth Acclaim. Manual — part 321
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).

TEST
EXTEND OR RETRACT ANTENNA
(1) To extend antenna, attach the positive (+) lead
of a 12 volt power source to the green antenna lead
and the negative (-) lead to the gray antenna lead.
(2) To retract antenna attach the positive (+) lead
of a 12 volt power source to the white antenna lead
and the negative (-) lead to the green antenna lead.
(3) If the motor will not operate, replace the an-
tenna assembly.
(4) If the motor runs freely and the antenna does
not extend or retract, the mast or drive assembly is
at fault.
(a) Remove the mast and verify that all the drive
teeth are intact. If not replace mast.
(b) Check for a defective drive mechanism, if de-
fective replace antenna assembly.
(5) If the mast jumps or travel rate is slow during
operation or the motor labors.
(a) Check for bent mast. If bent replace mast.
(b) Check for dirty or corroded mast. If necessary
clean and lubricate.
(c) If cleaning the antenna sections does not
solve the problem, the antenna mast should be re-
placed.
(6) If mast fails to extend or retract completely, or
motor continued to operate after full extension or re-
traction of mast.
(a) Check for broken teeth on the mast drive rod
or bent mast.
(b) Check limit switches, replace if necessary.
(7) If the mast checks good, the antenna assembly
should be replaced.

(8) Upon establishing that the fault is in the an-
tenna assembly, it may be traced to one or more of
the following conditions:
(a) Broken lead-in wire or shielding.
(b) Grounded lead-in wire or mast assembly.
(c) Moisture in support tube or lead-in assembly.
(d) Poor connection at antenna lead-in assembly
or shielding ground.
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove the right front fender splash shield fas-
teners and pull shield away from the wheel housing.
(3) Disconnect motor leads at the connector (Fig. 15).
(4) Disconnect lead-in cable by twisting at connec-
tor (Fig. 17).
(5) Remove one screw attaching antenna to an-
tenna brace (Fig. 18).
(6) Remove cap nut on fender surface with An-
tenna Nut Wench C-4816 (Fig. 11).
(7) Remove antenna from under fender.
INSTALLATION
(1) Position antenna under fender and through
fender adapter.
(2) Replace and tighten cap nut to 14 N
Im (125 in.
lbs.) torque with Antenna Nut Wench C-4816.
(3) Position antenna on antenna brace and install at-
taching screw. Tighten to 4 N
Im (40 in. lbs.) torque.
(4) Connect antenna lead at twist connector.
(5) Connect motor leads at connector.
(6) Position right front fender splash shield and in-
stall attaching fasteners.
(7) Connect negative battery cable and test opera-
tion of antenna.
POWER ANTENNA MAST
REMOVAL
(1) Remove cap nut using Antenna Nut Wrench
C-4816.
(2) Install temporary nut provided with the re-
placement mast.
(3) Turn ignition key to ACCESSORY position and
turn on radio.
(4) While the mast is moving up pull upward to re-
move mast and drive rod from the mast tube.
INSTALLATION
(1) Insert new drive rod into mast tube with drive
teeth toward antenna motor (Fig. 19).
(2) Turn off radio and guide mast into tube. The
mast may not be fully lowered when first installed.
(3) Replace the temporary nut with the original
cap nut and tighten to 14 N
Im (125 in. lbs.) torque
using Antenna Nut Wench C-4816.
(4) Turn radio on and off to extend and retract an-
tenna. Mast should be fully lowered after recycling.
