DIAGNOSIS AND TESTING (Continued)
Refer to Group 8W, Wiring Diagrams for the proper
connector.
(4) If fuse still blows, the problem is not the ampli-
fier. If fuse does not blow, replace the amplifier.
(5) If shorted or open circuit, repair as necessary.
MANUAL ANTENNA
Check for short or open circuits with an ohmmeter
or continuity light once the antenna cable is discon-
nected from the radio. The radio coax cable has a
connector that connects behind the between passen-
ger seat and console.
(1) Continuity should be present between the
antenna mast and radio end pin of antenna cable
plug (Fig. 1).
(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 in the trunk right rear quarter panel

POWER ANTENNA

(1) To extend antenna, using jumper wires, attach
one end to a battery positive source and the other to
the red and green wire terminals for up direction.
Connect the second lead to a good ground or to the
antenna mounting bracket (Fig. 2).
(2) To retract antenna attach the battery positive
source to the red wire terminal for the down direc-
tion. Connect the second lead to a good ground or to
the antenna mounting bracket.

(3) If the motor will not operate, replace the
antenna assembly.
(4) If the motor runs freely and the antenna does
not extend or retract, the mast or drive assembly is
at fault. Remove the mast and verify that all the
drive teeth are intact. If not replace mast.
(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 mast and clean it as neces-
sary. If corroded, replace mast.
(c) If cleaning the antenna sections does not
solve the problem, the antenna mast should be
replaced.
(6) If mast fails to extend or retract completely, or
motor continued to operate after full extension or
retraction of mast. Check for broken teeth on the
mast drive rod or bent mast.
(7) If the mast checks good, the antenna assembly
should be replaced.
(8) Upon establishing that the fault is in the
antenna 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.
(c) Moisture in support tube or lead-in assembly.
(d) Poor connection at antenna lead-in assembly
or shielding ground.
