Are you a fan of the video game Red Alert? Even if you're not, a Tesla coil may not be unfamiliar to you. Basically, a Tesla coil is a man-made device that was invented in the late 19th century. It generates a high voltage of electricity. Similarly, your car's ignition system is like mini-Tesla coil because the system creates and processes electricity. Just like the Tesla coil, your vehicle uses an ignition coil to amplify your battery's primary charge into high-voltage electricity.
This coil is a pulse transformer that converts low-voltage energy from your battery's initial 6 or 12 volts to tens and thousands of volts. It's composed of primary and secondary windings, which route low-voltage energy until they are induced with the current needed for a high-voltage transformation. As the high current exits the terminals, it is then directed to the spark plugs, where it is used to start the engine.
Since your car can generate that much power, it needs to be tapped properly. To do this, it needs a sturdy and reliable ignition coil. With its help, your car's own Tesla coil can perform its function properly. Now you won't see Red Alert-like Tesla coil pulses that zap opposing soldiers, but it does keep your car going, and that's what matters.

  • Steps on Installing a New Ignition Coil 11 January 2013

    The cost of installing a new ignition coil ranges from $120 to $200 depending on the type and size of the engine, so if you have the right tools and a bit of DIY skill, you can certainly save a lot of money if you change the ignition coil yourself. In this guide, we'll show you how you can replace the ignition coil in your car:

    Required skill level: Intermediate

    Needed tools and materials:

    1. Screwdriver
    2. Socket wrench

    Pulling out the wires

    With the hood propped open and the ignition key turned off, disconnect the negative battery terminal and unplug the wires running from the center of the ignition coil to the distributor cap. Make sure that the wires don't get mixed up. Take note that vehicles with conventional points have a green wire that leads from the side of the distributor and goes into the negative side of the coil. Cars with points replacement units, on the other have, have a red wire that goes into the positive side of the coil and a black one that goes into the negative side.

    Removing the oil coil

    Loosen the coil mounting bolts and remove the old ignition coil from the distributor cap. The coil is likely to be attached to the mounting bracket by a single bolt, so you will have to loosen this bolt as well to remove the coil as well. If the coil also comes with a rubber insulator and carbon button and spring, remove them as well.

    Preparing for installation

    Clean the cavity where you removed the ignition coil and install a new carbon button and spring or rubber insulator if necessary. Make sure to coat the rubber with dielectric tune-up grease before putting it back in its place.

    Installing the new coil

    Install the new coil into the cavity and secure the two leads into the cap connector. Once the coil is in place, insert and tighten the coil mounting brackets and plug all the wires back into the coil, double-checking that the positive and negatives wires go to their respective terminals. Reconnect the negative battery terminal, close the hood, and test drive the car.

  • Important Facts You Need to Know About Ignition Coil 21 December 2012

    Your vehicle's ignition coil is the important auto part that amps up the battery's 12-volt output into the roughly 20,000 volts what transforms the storage battery's 12 volts to the thousands of volts needed to fire the spark the plugs. The ignition coil does this feat with help from two windings wrapped around an iron core. As you turn your vehicle's key in the ignition, electricity starts to pass through the heavy wire turns in the primary winding. This creates a magnetic field around the primary and secondary windings. Breaker points in the ignition coil disrupt the circuit and cause this magnetic field to collapse. In turn, the change creates an high-voltage electrical current in the ignition coil's secondary windings. This current is what gets sent to the distributor for feeding into the spark plug. So without a functional ignition coil, you'll never be able to make it on the battery's power output. Make sure your ignition system generates enough power to jumpstart the fuel combustion process; check the condition of your vehicle's ignition coil.
