1. Safety First:
* Turn off all accessories: Make sure both vehicles have their headlights, radios, and other accessories turned OFF. This reduces the load on the batteries and prevents potential sparks.
* Park on a level surface: This ensures proper ground contact.
* Engage parking brakes: Secure both vehicles.
* Wear safety glasses: In case of battery acid splashing.
* Gloves are recommended: To protect your hands from acid and potential burns.
2. Identify Batteries:
* Locate the batteries: Dodge diesel trucks often have the battery located under the hood (although some models may have it elsewhere, possibly in the driver's side wheel well), but it’s always best to check your owner's manual. Diesel trucks sometimes have two batteries.
* Positive (+) and Negative (-) Terminals: Clearly identify the positive (+) and negative (-) terminals on both batteries. They are usually clearly marked.
3. Connect the Jumper Cables:
* Connect the Positive (+) to Positive (+): Attach one end of the red jumper cable to the positive (+) terminal of the DEAD battery in your Dodge diesel.
* Connect the Positive (+) to Positive (+): Attach the other end of the red jumper cable to the positive (+) terminal of the GOOD battery in the other vehicle.
* Connect the Negative (-) to Negative (-): Attach one end of the black jumper cable to the negative (-) terminal of the GOOD battery.
* Connect the Negative (-) to Ground: Crucially, for diesel vehicles, DO NOT connect the black jumper cable directly to the negative (-) terminal of the dead battery. Instead, connect it to a substantial, unpainted metal part of the engine block or chassis of the dead vehicle, away from the battery and moving parts. This helps avoid sparks near the battery.
4. Start the Good Vehicle:
* Let the running vehicle charge the dead battery for at least 5-10 minutes. This allows sufficient charge to transfer.
5. Attempt to Start the Dodge Diesel:
* Try starting your Dodge diesel. If it doesn't start immediately, try again after another few minutes of charging.
6. Disconnect the Jumper Cables:
* Reverse the order: Disconnect the cables in the reverse order you connected them. First, remove the black cable from the engine block/chassis, then from the good battery's negative terminal. Then remove the red cable from the good battery's positive terminal, and finally, from the dead battery's positive terminal.
Important Considerations for Diesel Vehicles:
* Dual Batteries: Many diesel trucks use two batteries. You may need to jump-start both. Consult your owner's manual for the proper procedure.
* Glow Plugs: Diesel engines require glow plugs to preheat before starting, especially in cold weather. Make sure your glow plug system is working correctly. Allow ample time for them to preheat. A faulty glow plug system can prevent the engine from starting, even with a good jump.
* Low Battery: A jump start might only be a temporary fix. If your battery is consistently low, you may have a charging system problem (alternator) that needs professional attention.
* Professional Help: If you are uncomfortable performing this procedure yourself, seek professional help from a roadside assistance service or a mechanic.
Always consult your vehicle's owner's manual for specific instructions and safety precautions. This information is for general guidance and may not apply to all Dodge diesel models.
