THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 08-03-96 DATED
FEB 2, 1996, AND NOTED IN THE 1996 SERVICE BULLETIN MANUAL (PUBLICATION NO. 81-699-97010). THIS IS A COMPLETE REVISION AND NO **ASTERISKS** ARE USED TO HIGHLIGHT THE CHANGES.

SUBJECT:
AM Radio Reception

OVERVIEW:
This bulletin involves attaching a shield and a capacitor to the ignition coil module, adding a jumper harness, ground strap and tie-strap.

MODELS:
1996 - 2000 (NS) Town & Country/Caravan/Voyager
1996 - 2000 (GS) Chrysler Voyager (International Market)

NOTE
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 3.3L OR 3.8L ENGINE.

SYMPTOM/CONDITION:
Vehicle operator complaint of poor AM radio reception due to ignition noise (static that varies with engine RPM) on low power/distant stations.

DIAGNOSIS:
If the vehicle operator describes the condition, tune in a weaker station. If static that varies with engine RPM is heard check the antenna connection, the antenna ground, the ground straps across the right side motor mount, and from the back of the engine to the dash panel. If these check ok but the static condition still exists, perform the Repair Procedure.

12. Attach the ground strap from the wiring package (using the existing fasteners) to the right strut assembly and the wheelhouse panel. Flattening out the anti-rotation tabs of the ground strap eyelets (if so equipped) may be helpful. Tighten the ground strap terminal and bracket attaching bolt on the strut assembly to 13.5 Nm (120 in. lbs.), tighten the attaching bolt to the wheelhouse panel/frame to 11 Nm (95 in. lbs.), Figure 6.
13. Center the front wheels and lower the vehicle.
14. Connect the negative battery cable and set the clock to the correct time.
