Testing chainsaws with a multimeter is a relatively simple procedure, but you need to know what you’re doing. 

While it may seem like a good idea to try to do this without proper guidance, you will likely injure yourself in the process. 


A chainsaw is a high-powered rotary tool with a sharp blade. Always refer to the user manual first for any troubleshooting advice before attempting any repairs yourself. Failure to exercise caution may lead to severe injury, or even death.

Testing coils with a multimeter 

This test checks if your chainsaw coil is still working. You will Obviously need a multimeter to perform this test. 

This is a simple test, so it’s perfect for people new to electronics. The first step is to find the coil. This can be difficult at times, especially if you are not familiar with how a chainsaw works. 

  1. First make sure the chainsaw is off and the engine is cool to the touch. 
  2. Then place the chainsaw on a flat surface and remove the spark plug boot. 
  3. To test a chainsaw with a multimeter, first hold the chainsaw by the handle and chain brake. 
  4. Adjust the spinning saw to operate at a fast but manageable speed. 
  5. Holding the saw still, place the multimeter on one of the bare wires of the chainsaw. 
  6. Next, connect the multimeters to the positive and negative terminals of the chainsaw coil. Remember to connect the black wire to the negative terminal and the red to the positive terminal. 
  7. Then check the resistance. 

If the multimeter shows a working saw, no troubleshooting is required. If the chainsaw fails the test, you need to replace the coil. 

If you intend to test chainsaw coils, you need a multimeter; an analog multimeter is fine. You also need a good and functional chainsaw. 

Make sure you know what part you are testing. If you are testing a coil, make sure it is the coil you are testing; if you’re testing a capacitor, make sure it’s a capacitor. 

More on Chainsaw Coils 

One of the most common things you need to do when using a chainsaw is to replace the chainsaw coil when the chainsaw coil stops working properly. A coil is a common electrical component used in chainsaws. 

A chainsaw coil is a simple electrical device that converts electricity into motion. It is basically a small electric motor. The motion is used to rotate the wood cutting chain. 

If you own a chainsaw, you know that this is a part that you have to replace very often. The chainsaw coil is the part of the chainsaw that produces electricity to run the chainsaw. 

The coil of chainsaw is just like a car engine; it has to work for the car to work. This is a very complex part, and many parts go into making the coil work. 

Although it may seem like a simple device, there are several factors that determine how fast a chainsaw cuts wood. This includes motor power, bar, blade type and how well the chain is sharpened. 

But all these factors depend on the quality of the chainsaw. The chainsaw must be able to run smoothly. The speed of the chainsaw can be determined by the power provided by the motor. 

Things to remember 

Although chainsaw coils are easy to design, it is important to test them correctly. This way you can be sure that the chainsaw is working properly and safely when you use it. 

The first step is to read the instructions for your chainsaw. Chainsaws are made by many different companies, and each company has its own chainsaw coil design. There are a few things to keep in mind when testing a chainsaw coil with a multimeter: 

  • To avoid damaging the multimeter and the coil being tested, you must make sure you are using the correct multimeter setting. 
  • The easiest way to do this is to set it to ohms. 
  • When you test resistance with a multimeter, the reading will change depending on which part of the coil you touch. 
  • When testing the resistance between the two ends of the coil, the reading should be close to zero. 
  • When testing the resistance between each leg of the coil, the reading will be infinite. 
  • Make sure your chainsaw is unplugged! Chainsaws can kick you and hurt you, so it goes without saying and we want to avoid that. 

The coil can get hot during testing, so it’s a good idea to let the chainsaw cool before testing. Otherwise, you might get burned. 

The most important part of testing a chainsaw coil with a multimeter is the coil itself. If you don’t have a good coil, you won’t get a good measurement. You should also be aware that while some chainsaws only have two wires, others have four. 

Chainsaw Replacement 

The chainsaw coil is the most important part of the chainsaw because it creates and controls the spark that ignites the gas in the saw’s carburetor. If your coil is not working properly, your chainsaw will not start. So, you should know how to test the coil to see if it is in good working condition.

chainsaw coils tend to have a short lifespan, so you may need to replace them at some point. Changing the coil is easy, but remember that your chainsaw may have two coils, one of which is inside a plastic cylinder that you will need to take to the store when you buy replacement coils. 

Before doing anything, you need to find out which coil you need to replace. If you are not sure which one is faulty, test them both with a multimeter. 

The chainsaw is the hands-down king of America’s yard-waste removal department. It’s a tool most Americans never think about but should. The fact is that a well-maintained chainsaw is an effective and efficient tool for cutting firewood and clearing brush and can last for decades if properly maintained.
