How to Test Chainsaw Ignition Coil With Multimeter
To test a chainsaw ignition coil with a multimeter, you’ll need to connect the leads of the multimeter to the primary and secondary terminals on the coil. You should see a reading of around 3 ohms on the multimeter. If the reading is higher or lower than this, it indicates that there may be a problem with the coil.
- Make sure that the chainsaw is turned off and disconnect the spark plug wire from the spark plug
- Remove the ignition coil cover and locate the primary and secondary terminals on the coil
- Connect one lead of the multimeter to the primary terminal, and touch the other lead to the ground (metal) surface of the chainsaw
- With the multimeter set to Ohms (Ω), note the reading onthe display
- It should be close to zero ifthe coil is working properly
- If not,replace it with a new one
- To testthe secondary winding, connect one leadof themultimeter tothesecondaryterminal,andtouchtheotherleadtooneofthesparkelectrodesintheplugboot(notconnectedtotheplug)

How to Test Small Engine Ignition Coil Without Multimeter
If your small engine isn’t starting up like it used to, one possible issue could be the ignition coil. Testing the coil with a multimeter is a quick and easy way to see if it’s working properly. Here’s how:
First, disconnect the spark plug wire from the spark plug. Then, use your multimeter to test the resistance of the coil by touching the leads to the terminals on the coil. The resistance should be within manufacturer specifications (usually between 0.5 and 2 ohms).
If the resistance is outside of those specs, then you’ll need to replace the ignition coil. But if it falls within that range, then you can move on to testing for continuity. To do this, simply touch one lead of your multimeter to each terminal on the coil while watching for continuity on the meter itself.
If there is continuity, then that means there’s a good connection between those points and you can rule out the ignition coil as being faulty.
Chainsaw Ignition Coil Resistance
If your chainsaw won’t start, the ignition coil may be to blame. The ignition coil is responsible for providing the spark that ignites the fuel in the cylinder. Over time, the coil can break down and become damaged, which will cause it to lose its ability to create a spark.
One way to test if your ignition coil is faulty is to measure its resistance. This can be done with a multimeter. Simply set the multimeter to ohms and touch the probes to the two terminals on the coil.
If the reading is outside of the normal range, then you likely have a problem with your ignition coil and will need to replace it.
Echo Chainsaw Ignition Coil Test
If your chainsaw won’t start, one of the first things you should check is the ignition coil. This is a relatively easy test that only requires a few tools.
To test the ignition coil on your chainsaw, you will need a spark tester and a multimeter.
First, disconnect the spark plug boot from the spark plug. Then, attach the spark tester to the end of the spark plug wire. Next, turn on the chainsaw and pull the trigger.
If there is a strong spark between the electrodes on the tester, then the ignition coil is working properly.
If there is no spark or if it is weak, then you will need to use a multimeter to test for continuity across the primary and secondary windings on the ignition coil. If there is no continuity, then it’s likely that the ignition coil needs to be replaced.
Stihl Chainsaw Ignition Coil
An ignition coil is a device used in many internal combustion engines to produce the high-voltage pulses needed to fire the spark plugs. The Stihl company produces chainsaws with two-stroke engines, and these require an ignition coil to function. If your Stihl chainsaw isn’t starting, one possible reason is a faulty ignition coil.
In this article, we’ll show you how to test the ignition coil on a Stihl chainsaw to see if it’s the problem.
Husqvarna Chainsaw Ignition Coil
If you’re having trouble with your Husqvarna chainsaw ignition coil, there are a few things you can check before taking it to a professional. First, make sure that the spark plug is properly gapped and that the spark plug gap isn’t too wide. Next, check the air filter to see if it’s clean and unobstructed.
Finally, inspect the flywheel key to ensure that it’s not damaged or worn down. If all of these things look good, then it’s likely that the ignition coil itself is defective and will need to be replaced.
Chainsaw Bad Coil Symptoms
If your chainsaw’s coil is going bad, there are a few symptoms that you may notice. The chainsaw may run erratically or not at all. If it does run, it may be at a lower RPM than usual and may misfire frequently.
The saw may also produce a lot of sparks and smoke.
How to Test Trimmer Ignition Coil With Multimeter
If your trimmer’s engine won’t start, the ignition coil may be to blame. You can test the ignition coil with a multimeter to see if it is receiving enough voltage. If the coil is not receiving enough voltage, it will need to be replaced.
To test the ignition coil, first disconnect the spark plug wire from the spark plug. Then connect one lead of the multimeter to the end of the spark plug wire and touch the other lead of the multimeter to one of the terminals on the ignition coil. The meter should read between 3 and 5 volts.
If it does not, then the ignition coil needs to be replaced.

How Do You Check a Coil on a Chainsaw?
If your chainsaw isn’t starting, one possible issue could be the coil. The coil is responsible for providing spark to the engine, so if it’s not working properly, the saw won’t start. To test whether the coil is faulty, you’ll need a multimeter.
Once you have one, follow these steps:
1. Remove the spark plug from the chainsaw and connect it to the end of the high-tension lead (the wire that goes from the ignition system to the spark plug).
2. Make sure that all other wires are disconnected from the coil so that you don’t accidentally shock yourself.
3. Touch one of your meter’s probes to ground (the black or green wire on most meters) and touch the other probe to either terminal on the coil.
4. If your meter reading is above 5,000 ohms, then your coil is functioning properly and you just need to look into another issue with your chainsaw.
How Do You Test an Ignition Coil With a Multimeter?
If you suspect that your ignition coil may be failing, you can use a multimeter to test it. First, disconnect the negative terminal of your battery. Then, remove the spark plug wire from the coil and attach the red lead of your multimeter to the end of the wire.
Next, touch the black lead of your multimeter to one of the bolts holding down the coil. Finally, have someone crank over the engine while you observe the reading on your multimeter. If it is functioning properly, you should see a reading between 6k-10k ohms.
How Do You Test a 2 Cycle Ignition Coil?
When testing a two-cycle ignition coil, you will need a multimeter. You will first want to disconnect the kill switch and the spark plug. Next, locate the primary winding on the side of the coil with the larger wire.
The other side is the secondary winding. To test the primary winding, set your multimeter to ohms and touch one lead to each terminal on the primary side of the coil. If it reads infinity, then the primary winding is good.
If it reads zero or close to zero, then there is a short in the primary winding and it needs to be replaced. To test the secondary winding, set your multimeter to AC volts and touch one lead to each terminal on the secondary side of the coil. If you get a reading of around 5-10 volts, then that means that your ignition coil is working properly!
How Many Ohms Should a Ignition Coil Have?
If you’re asking how many ohms should a ignition coil have, the answer is that it depends on the specific ignition coil. However, most aftermarket Ignition coils will have an internal resistance between 1.5-3.0 ohms.

Conclusion
If your chainsaw isn’t starting, one possible problem is the ignition coil. To test it with a multimeter, first make sure that the kill switch is in the “off” position. Then remove the spark plug boot and attach one lead of the multimeter to the spark plug terminal.
Next, touch the other lead of the multimeter to the exposed metal on the side of the ignition coil (not where it’s attached to anything). If you get a reading between 0.5 and 1.5 ohms, then your ignition coil is working properly.
