How to Test a Chainsaw Coil With a Multimeter

To test a chainsaw coil with a multimeter, first make sure the chainsaw is off and disconnected from any power source. Next, set the multimeter to the Ohms setting. Make sure that all spark plug wires are removed from their respective plugs.

Place one of the probes of your multimeter against each terminal on the coil itself. If you get a reading between 0-2 ohms then it indicates that your coil should be working correctly; if you don’t get any reading at all then it could mean there is an issue with your coil. If necessary, replace or repair your coils as needed until desired readings have been achieved.

  • Step 1: Gather the necessary tools
  • You will need a multimeter, wire cutters, and safety equipment like goggles and gloves
  • Step 2: Disconnect the spark plug wire from the chainsaw
  • This should be done before testing any electrical component in an engine
  • Step 3: Use the wire cutters to expose one end of the coil’s primary winding wires that are connected to the saw’s flywheel magnets on either side of it
  • Step 4: Set your multimeter to measure ohms (resistance)
  • Place one lead of your multimeter onto each exposed end of the coil’s primary winding wires and note down its reading once you have taken it
  • The value should match what is printed on or near your saw’s model number label or given in its owner’s manual
  • Step 5: Test for continuity with your meter by setting it to measure AC voltage and placing both leads across each exposed ends of secondary windings again noting down reading if available
  • If this test reveals no continuity then you may need to replace your coils entirely as they are likely faulty

How Do You Check a Chainsaw Coil?

To check a chainsaw coil, first make sure that the spark plug is disconnected. Then remove the flywheel cover from your saw and inspect the coils for signs of wear, corrosion or damage. If you find any of these issues then it may be time to replace the coil.

Next, use an ohmmeter to test both primary and secondary resistance in your ignition system. The readings should match what is listed in your chainsaw manual, otherwise it could indicate a faulty coil. Lastly, if all tests come back normal but your saw still isn’t starting correctly then you should consider replacing the coil altogether as it may be damaged beyond repair at this point.

How Do You Test a Small Engine Ignition Coil With a Multimeter?

Testing a small engine ignition coil with a multimeter is fairly straightforward, but it’s important to make sure you have the right type of multimeter for the job. The most common type of multimeter used for this purpose is an ohmmeter or continuity tester. To begin testing, disconnect the spark plug wire from the coil and turn on your meter.

Set it to measure resistance in ohms (Ω) then touch one probe tip to each terminal on the coil; if there’s no reading or an unusually high reading, replace the coil. If there’s a normal reading between 0-20K ohms, then you can be confident that your ignition coil is good.

How Do You Check Coil Resistance With a Multimeter?

To check coil resistance with a multimeter, you will first need to identify the two terminals of your coil and then connect them to the multimeter. Once connected, set your multimeter to measure ohms and make sure it is in a low range such as 200Ω or 2KΩ. Then touch one of the probes on each terminal of the coil.

The reading displayed by the multimeter should be close to zero if there is no resistance present in the circuit. If there is any resistance present, it will show up as a certain number of ohms depending on how much resistance is present in the circuit.

How Do You Test a 2 Stroke Ignition Coil?

Testing a 2 stroke ignition coil requires first disconnecting the power to the vehicle and then removing the spark plug cables from the coils. Once these steps have been taken, an ohm meter can be used to measure the primary resistance of each coil. The readings should not vary more than 10% between all of them.

Next, use a 12-volt test light and attach one lead to ground and touch it with other end of light against each secondary terminal on both coils while cranking engine over. Both will flash brightly if working correctly, otherwise one or both may remain dim indicating that either or both coils are faulty. Additionally, you may need to check for any breaks in wires leading from CDI unit as well as inspect connections on stator plate or flywheel magnets for corrosion or damage before replacing parts as necessary.

How to Test Ignition Coil Without Multimeter

Testing an ignition coil without a multimeter is possible in some cases. One way to test the coil is by using the “plug wire test.” This involves removing each spark plug one at a time and connecting them together, then cranking the engine while observing for sparks.

If there are no sparks observed when all of the plugs are connected, then it may be an indication that your ignition coil has gone bad.

Husqvarna Ignition Coil Resistance Specs

The Husqvarna ignition coil resistance specs are as follows: primary windings should have a resistance of 0.6 to 1.2 ohms and secondary windings should have a resistance of 5,000 to 10,000 ohms. It is important to check the resistance regularly for optimal performance and fuel efficiency from your lawn mower or other small engine.

Echo Chainsaw Ignition Coil Test

Testing your echo chainsaw’s ignition coil is a simple and straightforward process. First, disconnect the spark plug wire from the spark plug. Then, use an ohmmeter to measure the resistance between the two terminals on the ignition coil—the primary terminal should have 0-30 Ohms of resistance while the secondary terminal should generally range anywhere from 1,200-3,000 Ohms (depending on your model).

If either reading shows anything outside this range then it’s likely that you need to replace your ignition coil.

Chainsaw Ignition Coil Repair

If you’ve noticed that your chainsaw isn’t running as smoothly as it used to, the ignition coil may be in need of repair. The ignition coil is a key component of the engine and when it fails, it can cause poor performance or even prevent the chainsaw from starting at all. To diagnose and fix an ignition coil issue, you’ll need to remove the flywheel from the chainsaw and then inspect, test, and replace any faulty parts.

It’s important to remember that this type of repair should only be done by experienced professionals who have access to specialized tools for working on small engines.


Testing a chainsaw coil with a multimeter is an important and simple step to ensuring the proper operation of your saw. By following these steps, you can easily test the condition of your chainsaw’s coil and make sure it is in good working order. With regular testing, you can catch any potential problems before they become too serious, saving time and money in repairs down the line.

A well-maintained chainsaw will provide reliable service for many years to come!
