Lawn Mower Ignition Coil Wiring Diagram

A lawn mower ignition coil is a vital part of your lawn mower's engine. It converts the low voltage from the battery into the high voltage needed to fire the spark plugs. If your lawn mower's ignition coil is not working properly, it can cause the engine to misfire or not start at all. This article will discuss the different types of lawn mower ignition coils, how they work, and how to troubleshoot and replace a faulty ignition coil.

Types of Lawn Mower Ignition Coils

There are two main types of lawn mower ignition coils: *

Permanent magnet ignition coils:

These coils use a permanent magnet to generate the high voltage needed to fire the spark plugs. *

Variable reluctance ignition coils:

These coils use a rotating magnetic field to generate the high voltage needed to fire the spark plugs. Permanent magnet ignition coils are more common on older lawn mowers, while variable reluctance ignition coils are more common on newer lawn mowers.

How Lawn Mower Ignition Coils Work

When the ignition switch is turned on, the battery sends a low voltage signal to the ignition coil. The ignition coil then uses this signal to generate a high voltage spark. This spark is sent to the spark plugs, which ignite the fuel in the engine. The ignition coil is a critical part of your lawn mower's engine, and it is important to make sure that it is working properly. If your lawn mower is misfiring or not starting at all, it is possible that the ignition coil is faulty.

Troubleshooting a Faulty Lawn Mower Ignition Coil

If you think that your lawn mower's ignition coil is faulty, there are a few things you can do to troubleshoot the problem: 1.

Check the spark plugs:

The first thing you should do is check the spark plugs. If the spark plugs are fouled or damaged, they can prevent the ignition coil from generating a spark. 2.

Check the ignition wires:

The ignition wires connect the ignition coil to the spark plugs. If the ignition wires are damaged or corroded, they can prevent the spark from reaching the spark plugs. 3.

Check the ignition coil itself:

If the spark plugs and ignition wires are in good condition, the problem is likely with the ignition coil itself. You can test the ignition coil by using a multimeter.

Replacing a Faulty Lawn Mower Ignition Coil

If you have determined that the ignition coil is faulty, you will need to replace it. To do this, you will need to: 1.

Disconnect the battery:

Before you start, disconnect the battery to prevent any electrical shocks. 2.

Remove the old ignition coil:

The old ignition coil is usually held in place by a few bolts or screws. Remove these bolts or screws to remove the old ignition coil. 3.

Install the new ignition coil:

The new ignition coil should be installed in the same location as the old ignition coil. Make sure that the new ignition coil is properly connected to the battery and the spark plugs. 4.

Reconnect the battery:

Once the new ignition coil is installed, reconnect the battery.

Conclusion

The lawn mower ignition coil is a vital part of your lawn mower's engine. If your lawn mower's ignition coil is not working properly, it can cause the engine to misfire or not start at all. By following the steps in this article, you can troubleshoot and replace a faulty lawn mower ignition coil.
