How to Test a Chainsaw Coil

To test a chainsaw coil, start by turning off the engine and disconnecting the spark plug wire from the spark plug. Then remove any debris from around the ignition module or flywheel area with a brush. Next, make sure that all of the wiring is secure and properly connected to their respective terminals on both sides of the coil.

Finally, use an ohmmeter set to its highest resistance scale to measure between each terminal on one side of the coil and then compare those readings to manufacturer’s specifications. If either reading is outside of normal range, replace or repair your chainsaw’s ignition system components as needed.

  • Unplug the chainsaw from its power source: Before beginning any repairs or testing, it is important to make sure that the chainsaw is unplugged and can not be turned on accidentally
  • Remove the flywheel cover: The coil will be located beneath the flywheel cover which needs to be removed in order to access it
  • This may require a screwdriver or other tool depending on how your chainsaw is designed
  • Measure resistance of primary winding using an ohmmeter: Using an ohmmeter set to measure resistance, touch one lead of the meter against each terminal of the coil’s primary winding and read off the number shown by the meter’s display
  • It should measure between 0
  • 4 – 2 ohms in most cases; if it reads differently then this could indicate a problem with your coil and further investigation will be needed at this point
  • 4 Test secondary winding continuity: With two leads connected directly onto both terminals of the secondary winding, use an analog multimeter set to measure low voltage AC current along with a 12V battery as a power source for testing purposes; if there’s no reading then replace your coils as they are faulty and need replacing in such circumstances

How Do You Test a Chainsaw Coil With a Multimeter?

Before testing the chainsaw coil with a multimeter, it is important to ensure that all safety precautions are taken. This includes wearing protective clothing and disconnecting the spark plug wire from the engine. Once this has been done, you can begin testing the coil.

To do this, set your multimeter to ohms and place one of its probes on each terminal of the coil. If there is adequate resistance in between them, then your coil is functioning properly. However if there isn’t any resistance or if it reads infinite ohms, then you know that there might be an issue with your chainsaw’s coil and it should be replaced as soon as possible.

How Do You Test a 2 Stroke Coil With a Multimeter?

Testing a 2 stroke coil with a multimeter is relatively simple. First, make sure the engine is turned off and all connections are disconnected before beginning. Next, use your multimeter to set it to ohms (Ω) and attach the probes of the multimeter to each end of the ignition coil’s primary winding connection points.

If you get an open circuit reading or an infinite resistance measurement then there could be a problem with either wiring or insulation within the coil itself. If there is continuity between those two points then your 2 stroke coil should be working properly and ready for reassembly onto your bike!

How Do You Check Coil Resistance With a Multimeter?

To check the resistance of a coil with a multimeter, you need to first make sure that the multimeter is set to its ohms setting. Then look for two connectors on your coil and insert them into the probes of your multimeter. Once they are connected, press down on both probes until it clicks to ensure that there is a secure connection between them and the device.

After doing this, take note of the reading shown on your display; this will be the resistance value of your coil in ohms (Ω).

How Do You Test a 2 Stroke Coil?

To test a two-stroke coil, you will need to use an ohmmeter or multimeter. Start by connecting the multimeter’s red lead to one of the terminals on the coil and its black lead to another terminal. Then measure for resistance between the leads; there should be a reading of around 1–3 Ohms if it is in good condition.

If not, then you may have a faulty coil that needs replacing. After this, check for any shorts by measuring between each terminal and ground with your meter set on continuity mode; this should show no connection at all. Finally, connect 12V across both terminals and measure for spark output from each side – it should be strong enough to jump a 0.7 mm gap if working correctly!

How to Test Small Engine Ignition Coil Without Multimeter

Testing small engine ignition coils without a multimeter can be done by removing the coil and replacing it with another known working coil. If the engine runs normally after this switch, then it is likely that the original coil was faulty and needs to be replaced. If not, further testing may need to be done.

Chainsaw Ignition Coil Repair

When it comes to chainsaw ignition coil repair, the most important thing is to make sure you have a working spark plug. If your spark plug is faulty or not firing correctly, it can cause the chainsaw’s engine to misfire and run inefficiently. With that being said, if you’re noticing any of these symptoms with your chainsaw – reduced power output, poor acceleration, backfiring – then it may be time for an ignition coil replacement.

Fortunately, replacing the ignition coil on a chainsaw isn’t too difficult and often only requires basic tools and supplies such as new spark plugs and a screwdriver.

Husqvarna Ignition Coil Resistance Specs

The Husqvarna ignition coil is designed to provide a spark while maintaining optimal resistance. The primary winding of the coil should measure between 0.3 and 0.7 ohms, while the secondary winding should be between 4,000-6,200 ohms in order for the system to work properly. To test these values you will need an accurate multimeter or other device capable of measuring electrical resistance.

Chainsaw Ignition Coil Symptoms

A faulty ignition coil in a chainsaw can cause a number of symptoms, including difficulty starting the engine, an intermittent loss of power or stalling while running, and reduced fuel economy. If your chainsaw is experiencing any of these issues, it may be time to check the ignition coil for signs of wear or damage. Additionally, if you notice that your spark plug has black carbon deposits on it, this could also be an indication that the ignition coil needs replacing.


Testing a chainsaw coil is an important step in ensuring your machine will run properly and safely. By following the steps outlined in this blog post, you can test your chainsaw coil quickly and easily. In addition to testing the coil, it is important not to forget regular maintenance of your chainsaw like changing spark plugs and checking fuel lines.

Taking care of these basics will ensure that your chainsaw runs smoothly for years to come.
