Chrysler Stratus Convertible. Manual - part 248
ELECTRICAL NOISE DISTORTION ONE SPEAKER
• Remove output signal connector from (*) ampli-
fier and check for short to ground on the speaker
with the distortion. Refer to Group 8W, Wiring Dia-
grams for the appropriate pin numbers.
• If shorted to ground, disconnect speaker connec-
tor and recheck from the (*) amplifier for short to
ground.
• If still shorted to ground, repair wires. Not
shorted to ground, replace speaker.
• Not shorted to ground, check speaker resistance
at (*) amplifier connector for two to five ohms.
• If resistance is OK, refer to Radio Diagnosis. If
radio checks OK, replace amplifier.
• If resistance is less than two ohms, replace
speaker. If resistance is OK, repair wires
NOTE: (*) From radio if standard system.
MECHANICAL NOISE DISTORTION
• Check trim for loose parts, and speaker attach-
ments for buzzes, repair as necessary.
• Remove speaker while still connected and listen
for distortion. If distortion remains, replace speaker.
ONE SPEAKER NON-OPERATIVE
• Remove connector from (*) amplifier and check
for two to five ohms resistance to the non-operative
speaker. Refer to Group 8W, Wiring Diagrams for the
appropriate pin numbers.
• If resistance is less than two ohms, test speaker
for resistance.
• If OK, refer to Audio Diagnostic Test Procedures.
If not OK, replace speaker.
NOTE: (*) From radio if standard system.
ALL SPEAKERS NON-OPERATIVE
• Check radio for ON state, are the display lights
on
• Radio not ON, refer to Radio Diagnosis
• Check fuses, amplifier connectors and wires for
proper connection
• Check for good ground
• Check amplifier (if equipped with premium sys-
tem), for battery voltage and ON/OFF voltage
(1) Battery voltage OK and NO voltage at the
ON/OFF terminal, check for short or open in the
ON/OFF circuit.
(2) ON/OFF voltage OK, and NO battery voltage,
check for short or open in battery circuit.
(3) Prior to replacing amplifier check fuse 5 in the
Junction Block. If not OK, replace fuse. If fuse blows
again disconnect amplifier B+ wire connector. Refer
to Group 8W, Wiring Diagrams for the proper connec-
tor.
(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
once the antenna cable is disconnected from the
radio. The radio coax cable has a connector that con-
nects behind the between passenger seat and console.
(1) Continuity (less than 1 ohm) should be present
between the antenna mast and radio end pin of
antenna cable plug (Fig. 2).
(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
REMOTE CD CHANGER
CD changer inoperative.
(1) The CD changer receivers its power and
ground through the radio via the DIN connector. Ver-
ify that the radio powers up and functions before pro-
ceeding.
(2) With the radio turned ON, check the radio dis-
play when pushing the MODE/EJECT button to
select the CD mode.
(a) If the display shows “- - - -”, then insert a CD
magazine in the changer.
(b) If the display shows “nocd”, then insert a CD
into the magazine.
(c) If the display shows Err “xxxx”, then check
the error message table below.
