|Ground wires of the battery and the computer.|
|Transmission ground wire.|
|Ground wire of the the headlamps.|
|Throttle body ground wires|
|Clean battery terminals.|
In order to perform this job you will need a knife or a razor blade, a wire brush works best and most likely a 10mm socket to unbolt the screws and around 30 minutes of your time.
1. REMOVE the negative terminal cable from the battery in order to prevent any electrical hazards.
2. Find any ground wires on your car and inspect for a proper contact.
3. If you find any wires disconnect them using the 10mm wrench.
4. Carefully scrape off any paint off the surface until bare metal is seen.
5. Also clean the ground wire if it seems dirty.
6. Ensure all connections are clean and reconnect the wires to their proper location.
7. Reattach the negative terminal once you are done!
The benefits of this job will result in a better throttle response, less electric noise, stronger radio signal, quieter idle, faster starts, a louder stereo, faster computer response, smoother shifts, brighter headlights, brighter dashboard and slightly increased mpg. It all depends how many grounds you work on. As I have mentioned in my previous post, your battery will last longer if you regularly inspect the connections and they should be free of any dirt. Check your ground wires!
