Shocking Secrets of How to Jump Ignition Coil Revealed: Your Car Will Thank You!

Main points

  • The main reason for jumping an ignition coil is to get you to a mechanic or a repair shop so they can diagnose and fix the underlying issue.
  • Ensure that the positive (+) and negative (-) terminals on the new coil match the corresponding terminals on the existing wiring.
  • Before starting the engine, use a multimeter to check the continuity of the wires and ensure the new coil is functioning properly.

You’re on the road, cruising along, when suddenly your car sputters and dies. You check the engine, and the problem seems to be the ignition coil. You’ve heard about “jumping” the coil, but how do you actually do it? This guide will walk you through the process of how to jump ignition coil, explaining the basics, the necessary tools, and the step-by-step procedure.

The Basics of Ignition Coils

An ignition coil is a crucial component of your car’s engine. It’s responsible for transforming the low-voltage electrical current from your car’s battery into a high-voltage current that ignites the fuel in the spark plugs. When the ignition coil fails, your car won‘t be able to start or run properly.

Why Jump an Ignition Coil?

Jumping an ignition coil is a temporary solution to a faulty ignition coil. It allows you to get your car running again, but it’s not a permanent fix. The main reason for jumping an ignition coil is to get you to a mechanic or a repair shop so they can diagnose and fix the underlying issue.

Tools You’ll Need

Before you begin, make sure you have the following tools:

  • A working ignition coil: This could be a spare coil you have on hand or one borrowed from a friend or mechanic.
  • Wires: You’ll need wires to connect the new coil to the existing wiring.
  • Screwdriver: To remove the old coil and secure the new one.
  • Multimeter: To test the continuity of the wires and to ensure the new coil is working properly.
  • Safety Glasses: To protect your eyes from any potential sparks.

Safety Precautions

  • Disconnect the battery: Before you start working on the ignition coil, always disconnect the negative terminal of your car’s battery. This will prevent any electrical shock.
  • Work in a well-ventilated area: Avoid working in enclosed spaces, as the fumes from the car’s engine can be harmful.
  • Wear appropriate clothing: Make sure you’re wearing clothes that won’t get caught in any moving parts of the engine.
  • Use caution with tools: Handle all tools with care, and be aware of potential hazards.

Step-by-Step Guide to Jumping an Ignition Coil

Now that you have your tools and have taken the necessary safety precautions, you can begin the process of jumping your ignition coil:

1. Locate the Ignition Coil: The ignition coil is typically located near the spark plugs, often mounted on the engine block or cylinder head. Consult your car’s owner’s manual or online resources for the exact location in your specific vehicle model.

2. Remove the Old Coil: Using a screwdriver, remove the bolts or clamps that hold the old ignition coil in place. Disconnect the electrical connector from the coil.

3. Connect the New Coil: Carefully connect the new ignition coil to the existing wiring. Ensure that the positive (+) and negative (-) terminals on the new coil match the corresponding terminals on the existing wiring.

4. Secure the New Coil: Secure the new coil in place using the bolts or clamps that you removed from the old coil.

5. Reconnect the Battery: Once the new coil is securely installed, reconnect the negative terminal of the battery.

6. Test the Coil: Before starting the engine, use a multimeter to check the continuity of the wires and ensure the new coil is functioning properly.

7. Start the Engine: If everything is connected correctly, you should be able to start your car.

Troubleshooting

If your car still doesn’t start after jumping the ignition coil, there are a few other things you can check:

  • Spark Plugs: Make sure the spark plugs are in good condition and are properly gapped.
  • Fuel System: Check the fuel lines and fuel filter for any blockages.
  • Battery: Ensure the battery is fully charged.
  • Wiring: Inspect the wiring for any damage or loose connections.

A Word of Caution: Jumping is a Temporary Solution

Jumping an ignition coil is a temporary solution that should only be used in emergencies. It’s essential to understand that this method doesn’t address the underlying problem. A faulty ignition coil can be caused by various factors, including:

  • Worn-out coil: The coil itself may have reached the end of its lifespan.
  • Electrical issues: Problems with the wiring or other electrical components in the ignition system can affect the coil.
  • Overheating: The coil may have overheated, causing damage.

Time to Visit a Mechanic

If you’ve jumped the ignition coil, but your car is still experiencing problems, it’s time to take it to a mechanic. They can diagnose the underlying issue and recommend the best course of action.

Final Thoughts: A Jumpstart to Your Car’s Health

Jumping an ignition coil can be a lifesaver when your car suddenly stops working. It’s a simple procedure that can get you back on the road, but it’s crucial to remember that it’s only a temporary solution. If you’re experiencing problems with your ignition coil, it’s essential to have it inspected by a qualified mechanic to address the root of the issue.
