Battery Cable - Positive

This procedure covers removal and replacement of the positive battery cable on a 2005 Dodge Viper with 8.3L V10 engine, including disconnection from the battery terminal and all downstream connection points.

Warnings

Tools required

Parts

• Positive battery cable assembly × 1 — Use OEM specification

Preparation

1. Ensure ignition is off and key is removed from the vehicle.
2. Open the hood and secure it in the open position.
3. Locate the battery in the rear trunk compartment (accessed from behind the seats inside the cabin).
4. Allow engine to cool completely if recently driven.
5. Gather all tools and the replacement positive battery cable.

Procedure

1. 1

   Access the Battery
   Open the hood and locate the battery in the engine compartment. The battery on the 2005 Viper is located under the hood, not in the rear of the vehicle.
2. 2

   Disconnect Negative Battery Terminal
   Using a 10mm wrench, loosen the negative (black/ground) battery terminal bolt. Remove the negative cable from the battery post and secure it away from the battery to prevent accidental contact. This must be done before touching the positive cable.

3. 3

   Disconnect Positive Battery Terminal
   Using a 10mm wrench, loosen the positive (red) battery terminal bolt. Carefully remove the positive cable terminal from the battery post. If the terminal is stuck, use a battery terminal puller rather than prying to avoid damage. Move the cable away from the battery post and ensure it cannot contact any grounded metal.

   Trace and Document Cable Routing
   Before removing any cable mounting points, carefully trace the positive cable routing from the battery to the starter and power distribution center within the engine compartment. Note the path, any protective loom or conduit, and all mounting clip locations. Take photos if possible to ensure correct reinstallation routing.
5. 5

   Remove Cable Mounting Hardware
   Locate and remove all mounting clips and cable ties securing the positive battery cable along its route within the engine compartment. Carefully release any push-clips or fasteners holding the cable in place without damaging surrounding components.
6. 6

   Disconnect Starter Motor Connection
   In the engine compartment, locate the positive cable connection at the starter motor solenoid. Using a 13mm wrench or socket, remove the nut securing the positive cable terminal to the starter solenoid stud. Note that multiple cables may be stacked on this stud; remember the order for reassembly. Carefully separate the cable terminal from the stud.
7. 7

   Disconnect Power Distribution Center Connection
   Locate the positive cable connection at the Power Distribution Center (PDC/fuse box) in the engine compartment. Remove the protective cover if present. Using a 10mm or 13mm wrench as appropriate, remove the fastener securing the positive cable terminal to the PDC stud. Carefully separate the cable terminal from the connection point.
8. 8

   Remove Positive Cable Assembly
   With all connections and mounting points released, carefully pull the positive cable assembly from the vehicle. Thread it back through any grommets or conduits as necessary within the engine compartment. Inspect the old cable for signs of corrosion, fraying, or damage to understand the failure mode.
9. 9

   Prepare New Cable and Clean Connection Points
   Unpack the new positive battery cable and verify it matches the original in length, terminal configuration, and routing. Use a wire brush to clean all connection points: battery positive post, starter solenoid stud, and power distribution center stud. Remove any corrosion or oxidation to ensure good electrical contact.
10. 10

    Route New Cable
    Beginning from the battery end, route the new positive cable through the same path as the original, following the documentation and photos from step 4. Thread the cable through grommets and conduits, ensuring it does not contact any sharp edges, hot surfaces (exhaust components), or moving parts. Maintain proper separation from the negative/ground cables.
11. 11

    Connect to Power Distribution Center
    Install the positive cable terminal onto the appropriate stud at the Power Distribution Center. Hand-thread the fastener to ensure proper engagement, then tighten using a torque wrench. Apply a light coating of dielectric grease to the connection if desired. Reinstall any protective covers.
12. 12

    Connect to Starter Motor
    Install the positive cable terminal onto the starter motor solenoid stud. If multiple terminals stack on this location, ensure they are reinstalled in the correct order noted during removal. Hand-thread the nut to ensure proper engagement, then tighten securely. Ensure all connections on this stud are secure and properly seated.
13. 13

    Secure Cable Routing
    Working from the engine compartment back to the battery, reinstall all mounting clips, cable ties, and support brackets to secure the positive cable in its proper routing. Ensure the cable is supported at regular intervals and does not hang loose or contact any moving or hot components. Verify the cable path matches the original routing.
14. 14

    Connect Positive Battery Terminal
    Place the positive cable terminal onto the positive battery post. Ensure it is fully seated on the post. Using a 10mm wrench and torque wrench, tighten the terminal bolt to the specified torque. Do not overtighten, as this can damage the terminal or battery post. Apply dielectric grease to the connection if desired.

    Reconnect Negative Battery Terminal
    Place the negative cable terminal onto the negative battery post. Ensure it is fully seated on the post. Using a 10mm wrench and torque wrench, tighten the terminal bolt to the specified torque. The negative terminal is always reconnected last to prevent sparking during the positive cable installation.

Reassembly

1. Verify both battery terminals are tight and properly torqued.
2. Ensure no tools or parts are left in the battery compartment or engine bay.
3. Restore access panels, seat cushions, or seats to their normal position.
4. Close the hood and ensure it is properly latched.

Verification

• Turn the ignition to the ON position (do not start) and verify that dashboard lights illuminate normally, indicating proper electrical connection.
• Start the engine and verify it cranks and starts normally without hesitation.
• Check that all electrical systems function properly: lights, radio, power windows, climate control, etc.
• Visually inspect all connection points for any signs of arcing, heat discoloration, or loose terminals.
• With the engine running, verify the charging system is functioning by checking that battery voltage is approximately 13.5-14.5 volts.
• Ensure no warning lights related to charging system or electrical faults are illuminated on the dashboard.
