Battery Cables - Both

This procedure covers removal and installation of both positive and negative battery cables on the 2008 Dodge Viper with 8.4L V10 engine, including connections at the battery, starter, and ground points.

Warnings

Tools required

Parts

• Positive battery cable × 1 — Use OEM specification
• Negative battery cable × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake.
2. Turn ignition to OFF position and remove key.
3. Open hood and secure with hood prop.
4. Turn off all electrical accessories including headlights, radio, and climate control.
5. Allow engine to cool if recently operated.

Procedure

1. 1

   Disconnect negative battery cable
   Locate the battery in the engine compartment. Using a 10mm socket, loosen the negative battery terminal clamp bolt. Remove the negative cable from the battery post. If cable is stuck, use a battery terminal puller to avoid damaging the post. Position the cable away from the battery post to prevent accidental contact.
2. 2

   Disconnect positive battery cable
   Using a 10mm socket, loosen the positive battery terminal clamp bolt. Remove the positive cable from the battery post. Position the cable away from the battery to prevent accidental contact with ground or the negative terminal.
3. 3

   Remove positive cable from starter
   Access the starter motor from underneath the vehicle. Locate the positive battery cable connection at the starter solenoid. Using a 13mm socket, remove the nut securing the positive cable terminal to the starter solenoid stud. Remove the cable terminal from the stud. Note the presence of any other wires or cables sharing this connection point for proper reassembly.
4. 4

   Remove positive cable routing hardware
   Trace the positive cable from battery to starter, noting all routing clips and fasteners. Remove any retaining clips or fasteners securing the positive cable along its routing path. The cable typically routes along the frame rail and through protective conduit. Remove the complete positive cable from the vehicle.
5. 5

   Remove negative cable from engine ground points
   Locate the negative battery cable ground connection point on the engine block. Using a 13mm socket, remove the bolt securing the negative cable terminal to the engine block ground stud. The ground point is typically located on the driver side of the engine block near the cylinder head.
6. 6

   Remove negative cable from body ground points
   Locate the negative battery cable ground connection to the body or frame. Using a 13mm socket, remove the bolt securing the negative cable to the body ground point. This connection is typically on the frame rail or inner fender structure near the battery location in the engine compartment.
7. 7

   Remove negative cable routing hardware
   Trace the negative cable from battery through engine bay to ground points, noting all routing clips and fasteners. Remove any retaining clips or fasteners securing the negative cable along its routing path. Remove the complete negative cable from the vehicle.
8. 8

   Clean battery terminals and cable connections
   Using a wire brush, clean the battery posts thoroughly to remove any corrosion or oxidation. Clean all cable terminal ends, starter solenoid stud, and ground connection points. Ensure all mating surfaces are clean and free of corrosion for optimal electrical contact.
9. 9

   Install new negative cable routing and ground connections
   Route the new negative battery cable from the battery location through the vehicle following the original cable path. Connect the negative cable terminal to the body ground point and secure with the 13mm bolt. Connect the negative cable terminal to the engine block ground point and secure with the 13mm bolt. Reinstall all routing clips and fasteners along the cable path.
10. 10

    Install new positive cable routing and starter connection
    Route the new positive battery cable from the battery location to the starter following the original cable path. Reinstall all routing clips and fasteners along the cable path. Place the positive cable terminal onto the starter solenoid stud along with any other wires that share this connection. Secure with the 13mm nut, ensuring all connections are tight and properly seated.
11. 11

    Connect positive battery cable to battery
    Apply a thin coat of dielectric grease to the positive battery post. Place the positive cable terminal onto the positive battery post, ensuring it is fully seated. Using a 10mm socket, tighten the terminal clamp bolt securely. The terminal should not move when pulled by hand.
12. 12

    Connect negative battery cable to battery
    Apply a thin coat of dielectric grease to the negative battery post. Place the negative cable terminal onto the negative battery post, ensuring it is fully seated. Using a 10mm socket, tighten the terminal clamp bolt securely. The terminal should not move when pulled by hand. Expect a small spark when making final contact, which is normal.

Reassembly

1. Verify all cable connections are tight and properly routed away from hot or moving engine components.
2. Ensure no tools or loose items remain in the engine bay or trunk area.
3. Double-check that all routing clips and fasteners are reinstalled to prevent cable chafing or movement.

Verification

• Turn ignition to ON position (do not start) and verify all dashboard warning lights illuminate normally, then extinguish.
• Start the engine and verify it cranks and starts normally with no unusual sounds from the starter.
• Test all electrical accessories including lights, radio, climate control, and power windows to confirm proper operation.
• Visually inspect all cable connections for proper seating and tightness.
• Check that battery cables are properly routed and secured, with no interference with moving or hot components.
• Reset clock and radio presets as needed.
