Battery Terminal

This procedure covers the inspection, cleaning, and replacement of battery terminals on the 2005 Dodge Viper with 8.3L V10 engine, ensuring proper electrical connection and corrosion removal.

Warnings

Tools required

Parts

• Battery terminal (negative) × 1 — Use OEM specification if replacing
• Battery terminal (positive) × 1 — Use OEM specification if replacing

Preparation

1. Ensure ignition is off and key is removed from vehicle
2. Open trunk to access battery compartment located on driver side rear
3. Identify negative (black, marked with "-") and positive (red, marked with "+") battery terminals
4. Inspect terminals for corrosion, damage, or looseness before beginning work

Procedure

1. 1

   Disconnect Negative Battery Terminal
   Using a 10mm wrench, loosen the negative (black) battery terminal bolt by turning counterclockwise. Do not remove the bolt completely — loosen only enough to allow terminal removal. If terminal is stuck due to corrosion, use a battery terminal puller to avoid damaging the battery post. Lift terminal straight up and off the battery post, then position it away from the battery to prevent accidental contact.
2. 2

   Disconnect Positive Battery Terminal
   Using a 10mm wrench, loosen the positive (red) battery terminal bolt by turning counterclockwise. Remove terminal from battery post using the same technique as negative terminal. Position terminal away from battery and ensure it does not contact any metal surfaces or the negative terminal.
3. 3

   Inspect Terminals and Posts
   Examine both battery terminals for cracks, excessive corrosion, or damaged cable connection points. Inspect battery posts for corrosion buildup (white, blue, or green powdery deposits). Check cable insulation near terminals for cracking or damage. If terminals are severely corroded, cracked, or cable strands are visible/frayed, replacement is required rather than cleaning. Note: Close hood and verify proper closure
4. 4

   Clean Battery Posts
   Using a wire brush or battery post cleaning tool, thoroughly clean both battery posts by rotating the brush around each post until bare metal is visible. Remove all corrosion deposits. If heavy corrosion is present, apply baking soda and water solution to neutralize acid, let sit for 2-3 minutes, then scrub and wipe clean with a damp cloth. Dry posts completely before proceeding.
5. 5

   Clean Battery Terminals
   Using a wire brush or the terminal cleaning portion of a battery terminal tool, clean the inside contact surface of both terminals until bare metal is visible. Ensure all corrosion is removed from the contact area. If terminals are being replaced, verify new terminals are correct size and type for the battery posts (top-post style for 2005 Viper).
6. 6

   Apply Terminal Protectant (Optional)
   Apply a thin coating of dielectric grease or battery terminal protectant to the battery posts. This helps prevent future corrosion. Do not apply excessive amounts — a light coating on the post surface is sufficient.
7. 7

   Install Positive Battery Terminal
   Place the positive (red) terminal onto the positive battery post, ensuring it seats completely and makes full contact around the post. Align the terminal bolt and tighten using a 10mm wrench or socket with a torque wrench to specification. The terminal should be snug but not overtightened, which can damage the battery post or terminal.

8. 8

   Install Negative Battery Terminal
   Place the negative (black) terminal onto the negative battery post, ensuring complete seating and full contact. Tighten the terminal bolt using a 10mm wrench or socket with a torque wrench to specification. As with the positive terminal, avoid overtightening.

9. 9

   Apply External Terminal Protectant
   After terminals are secured, apply a thin coating of dielectric grease or terminal protectant spray to the outside of both terminals and the exposed bolt areas. This provides additional corrosion protection. Wipe away any excess.

Reassembly

1. Verify both terminals are tight and cannot be rotated by hand on the battery posts
2. Ensure no tools or conductive materials are left in the battery compartment
3. Close trunk and verify proper closure

Verification

• Turn ignition to ON position (do not start) and verify dash lights illuminate normally, indicating electrical system is functioning
• Start engine and verify normal cranking and starting operation
• Check that no warning lights related to electrical system or battery charging appear on instrument cluster
• Verify all electrical accessories function properly (radio, windows, climate control)
• Inspect terminals after 24-48 hours of normal driving for any signs of looseness or new corrosion
