You may have a lawnmower that needs a new ignition coil. You may also have an extra ignition coil lying around your garage. Are the coils interchangeable? The short answer is yes; ignition coils are interchangeable.
However, there are some things you need to take into consideration before making the switch.
A lawn mower usually has a carburettor, an ignition coil, and a distributor.
The carburettor mixes fuel, air, and spark to create a powerful explosion that ignites the mixture and starts the engine.
The ignition coil is a transformer that helps the carburettor work as efficiently. The ignition coil contains a lot of electrical energy that, when applied to the carburettor, helps the fuel mix properly.
The distributor controls the spark timing to allow for even firing of the engine.
This article will go over the things you need to know before replacing your lawn mower's ignition coil.
Luckily, ignition coils are easy to replace and can usually be done with just a few simple tools. Check the Specifications Before purchasing a replacement ignition coil, always check the specifications to make sure it is compatible with your lawn mower.
The short answer is yes. They are interchangeable. However, there are a few things you should consider before doing so.
If you're looking to change brands, you'll probably find more information about swapping ignition coils in our guide to buying a new lawn mower.
It provides an electrical path between the primary and secondary winding of the ignition system.
The coil is a large, heavy object with multiple wires woven into a cotton-like material. These coils are made in the same factory that makes your lawn mower.
When the coil receives power, it creates a magnetic field. This magnetic field causes electrons to flow through the coil. When the coil loses power, the magnetic field collapses and the electrons stop flowing.
There are several reasons why a lawn mower's ignition system could fail. One common reason is poor gas quality. Poor gas quality means that the gasoline isn't able to burn completely. It leaves behind unburned hydrocarbons that collect inside the combustion chamber.
These unburned hydrocarbons eventually build up until they reach a certain point where they cause the engine to misfire.
Another common problem is a dirty spark plug. Dirty plugs prevent the spark from reaching the cylinder walls.
A third potential issue is a loose connection between the battery and the ignition system. Loose connections can lead to corrosion and other problems.
The engine coil or starter coil is an essential component of your lawnmower. It is what transfers voltage from the battery to the spark plug, thus causing the spark that starts the mower.
A worn or damaged coil could cause your lawnmower to run poorly, fail to start, or even stall. In some cases, a blown motor may also occur.
By checking its condition, you can tell if your lawnmower's coil is bad. A good way to do this is to look at the spark plug wires. The coil is likely bad if you see any signs of damage or wear, such as fraying.
Another thing you should check is whether the spark plug is sparking when you turn the key. If it's not, then the coil is most likely bad.
If you have no idea how to test the coil, you can call the lawnmower manufacturer for assistance. They will be able to tell you if the coil needs replacing.
Yes, you can test a lawnmower's coil with a multimeter. You can use a digital multimeter (DMM) to measure resistance.
To test a lawnmower, you first need to remove the spark plug wires. Then, attach a voltmeter to the positive terminal of the battery. Next, connect the negative terminal of the voltmeter to the ground post on the lawnmower.
Next, place the voltmeter probe tip against the coil's centre tap. The centre tap is located near the middle of the coil.
Next, press down firmly on the trigger switch to start the lawnmower. Once the lawnmower begins running, slowly move the meter probes around the coil.
Once you've tested all four corners of the coil, note which corner has the lowest reading, the corner with the highest resistance.
This method works well because the coil's resistance varies depending on the amount of current being drawn. As a result, you'll get a more accurate measurement by testing the coil.
A working ignition coil will read between 2.5 5 k ohms. Set the positive lead in the position where the spark plug would normally be inserted. Place it across the coil. Observe the reading on the meter.
Replacing a lawnmower's ignition coil is fairly simple. Your local dealer or service shop should be able to help you out.
First, disconnect the spark plug wire. This allows you to access the coil without removing the spark plug.
Next, remove the old coil. Be careful not to touch the exposed terminals of the coil. Doing so could short them together and cause a fire hazard.
After removing the old coil, install the new one. Make sure that the new coil fits snugly into the slot.
Now, reconnect the spark plug wire. Turn the key to make sure that the lawnmower starts.
When you're done, replace the cover over the coils.
Your lawn mower ignition coils are important components of your lawnmower. It's best to keep an eye on them, especially if they show signs of wear and tear.
You can also test a lawnmower using a multimeter. In addition, you can replace the ignition coil yourself.
