Battery Cables - Both

Replace both positive and negative battery cables on the 1992 Dodge Viper, including battery terminal connections and engine block/chassis ground points.

Warnings

Tools required

Parts

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

Preparation

1. Ensure ignition is off and keys are removed from vehicle
2. Open hood and secure in raised position
3. Locate battery in engine compartment
4. Identify positive cable routing from battery to starter motor and any intermediate connections
5. Identify negative cable routing from battery to engine block and chassis ground points

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative battery terminal bolt. Remove the negative cable from the battery post and secure it away from the battery to prevent accidental contact. The negative terminal is marked with a minus (-) symbol or may be black in color.
2. 2

   Disconnect positive battery terminal
   Using a 10mm socket, loosen the positive battery terminal bolt. Remove the positive cable from the battery post. The positive terminal is marked with a plus (+) symbol or may be red in color. Keep this cable away from any ground surfaces.
3. 3

   Remove negative cable ground connections
   Locate the negative cable ground point on the engine block and the chassis ground strap. Locate the engine ground point on the engine block and confirm its exact position on this V10 before removal. Using a 13mm socket, remove the bolt securing the negative cable to the engine block. Remove the chassis ground strap bolt if present. Note the exact routing and mounting locations for reinstallation.
4. 4

   Remove positive cable starter connection
   Locate the positive cable connection at the starter motor. Verify the starter location on the 8.0L V10 (typically mounted low on the engine near the bellhousing); note the exact position before disconnecting. Using a 13mm socket, remove the nut securing the positive cable terminal to the starter solenoid stud. Note any additional positive cables or wires sharing this connection point, as they must be reinstalled in the same order.
5. 5

   Remove cable routing clips and fasteners
   Inspect the cable routing along the engine bay and frame. Remove any clips, ties, or fasteners securing the cables to the vehicle structure. Note the exact routing path for both cables to ensure proper reinstallation and avoid interference with moving parts or heat sources.
6. 6

   Clean all connection points
   Using a wire brush, thoroughly clean the battery posts, battery terminal clamps on the new cables, starter solenoid stud, engine block ground mounting surface, and chassis ground mounting surface. Remove all corrosion, oxidation, and debris. Clean surfaces ensure proper electrical conductivity and prevent future corrosion.
7. 7

   Install new positive cable to starter
   Route the new positive cable from the battery location to the starter motor following the original path. Connect the positive cable terminal to the starter solenoid stud, ensuring any additional wires are reinstalled in their original positions. Install the nut and tighten to the factory-specified torque for the starter solenoid stud (verify against Viper service manual) using a torque wrench. Apply dielectric grease to the connection if available.

8. 8

   Install new negative cable ground connections
   Route the new negative cable from the battery location to the engine block ground point following the original path. Ensure the ground mounting surfaces on the engine block are clean and free of paint or corrosion. Connect the negative cable terminal to the engine block and install the bolt. Tighten to the factory-specified torque (verify against Viper service manual). If a chassis ground strap is present, install it to the chassis ground point and tighten to the factory-specified torque. Ensure metal-to-metal contact at all ground points.

9. 9

   Secure cable routing
   Reinstall all cable routing clips, ties, and fasteners to secure both cables along their paths. Ensure cables are routed away from moving parts (belts, pulleys, fan), hot surfaces (exhaust manifolds, headers), and sharp edges. Verify adequate slack for engine movement and no interference with hood closure.
10. 10

    Connect positive battery terminal
    Place the positive cable terminal onto the positive battery post. Install the terminal bolt and tighten to the factory-specified torque for the battery terminal clamp (verify against Viper service manual). Do not overtighten as this can damage the battery post or terminal. Apply dielectric grease to the connection if available to prevent corrosion.

    Battery Terminal Bolts6 Nm (4 lb-ft)
11. 11

    Connect negative battery terminal
    Place the negative cable terminal onto the negative battery post. Install the terminal bolt and tighten to the factory-specified torque for the battery terminal clamp (verify against Viper service manual). Do not overtighten. This completes the electrical circuit. Apply dielectric grease to the connection if available.

Reassembly

1. Verify all cable connections are tight and secure
2. Ensure no tools or loose items remain in engine compartment
3. Close hood and verify proper operation

Verification

• Turn ignition to ON position (do not start) and verify dash lights illuminate normally
• Start engine and verify normal operation
• Check for proper charging system operation (battery warning light should extinguish after engine start)
• Verify all electrical accessories function normally (lights, radio, windows, etc.)
• Inspect all cable connections for signs of arcing, smoking, or excessive heat after brief operation
• Verify cables are properly routed with no interference or contact with hot/moving components
