NUMBER: 08-45-99GROUP: Electrical
DATE: Dec. 31, 1999
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.
PARTS REQUIRED:
1 05016107AA Shield Package
Contents Of Shield Package:
1-Suppression Shield, 2-Attaching Stud Assemblies, 2-Attaching Nuts
1 05016105AA Wiring Repair Package 1996-1998
1 05016106AA Wiring Repair Package 1999-2000
Contents of Wiring Packages:
1-Wiring Jumper, 1-Wiring Tie-Strap, 1-Ground Strap, 1-Ignition Noise
Suppression Capacitor, 1-Capacitor Mounting Bolt
REPAIR PROCEDURE:
1. Disconnect the negative battery cable.
Fig. 1:
2. Disconnect the electrical connector from the ignition coil module, Figure 1.
3. Remove the ignition coil module bottom-forward mounting bolt and discard.
Fig. 2:
4. Attach the supplied capacitor to the ignition coil module with the supplied bolt, Figure 2. Torque the screw to 10-15 Nm (85-125 in. lbs.)
5. Connect the single wire connector of the jumper harness to the suppression capacitor. Then connect the jumper harness between the ignition coil module and the powertrain harness connector, Figure 2.

Fig. 3A:
6. With the supplied tie-strap, tie back the extra length of the jumper harness to the main bundle of the powertrain harness (see fig. 3 or fig. 3a).
Fig. 4:
7. Remove and discard the two top bolts that mount the ignition coil module, Figure 4.
8. Replace the discarded ignition coil module mounting bolts with the supplied double-ended studs. Torque studs to 10-15 Nm (85-125 in. lbs.)
Fig. 5:
9. Install the shield over the double-ended studs and attach with two nuts from the shield kit, Figure 5. Torque the nuts to 10-15 Nm (85-125 in. lbs.).
10. Turn the ignition switch to the Unlock position so the steering wheel can rotate.
11. Raise vehicle. Then turn the front wheels to the left.
Fig. 6:
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.
POLICY: Reimbursable within the provisions of the warranty.
