How do I know if my chainsaw coil is bad?

The only certain test is to install a new one and test run the saw. Another symptom that indicates a bad electronic module or coil is spark that becomes weak when the saw gets hot. If a saw won’t start after refueling, chances are engine heat has weakened or eliminated the spark.

How do you check a chainsaw coil with a multimeter?

If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good. If there is no spark, it means the chainsaw coil will need to be replaced. Connect your multimeter to the positive terminal or pin of your coil, and to the high output terminal that goes to the spark plug.

How does a chainsaw ignition coil work?

Electrical currents run through the ignition coil and transmit electricity to the spark plug. The electricity creates sparks within the spark plug, and the sparks ignite the fuel in the engine, enabling the chain saw to run. Testing the ignition coil at home is simple to do and requires minimal tools.

How many ohms should a ignition coil have?

Most ignition coils should have a primary resistance falling somewhere between 0.4 and 2 ohms; however, refer to your manufacturer’s specifications for the correct reading. If a reading of zero is displayed, that signifies that the ignition coil has shorted internally in the primary windings and needs to be replaced.

How do you check coil resistance with a multimeter?

Turn your multimeter dial to the lowest ohms setting, usually 20 or 200. Place the two probes on the atomizer your coil is in, one probe on the positive pin (the one in the middle of the 510 connection), and the other on the outside 510 threading, to get the total resistance of the coil in the atomizer.

How do you test a small ignition coil with a multimeter?

If you have a multimeter, turn its dial to the 20 K ohm scale, and insert its red lead in the common jack and its black lead in the jack marked with the ohm symbol. Test the meter before checking continuity by touching the leads together and verifying that you get a reading close to 0.

How do you test the coil of a chainsaw?

You must consider attaching the spark plug tester to the wires of the coil of your chainsaw, instead of connecting the spark plug back to the wires. For this, you will have to ground the alligator clips and then try cranking the engine to see any spark in the tester’s gap.

When to replace ignition coil on Echo chainsaw?

What does it mean when a chainsaw coil is not working?

If you see any bright blue sparks jumping inside the spark plug gap when you try cranking the engine of your chainsaw it means that the coil of your chainsaw is working properly. The bright blue spark is visible clearly in daylight but if you don’t see any spark it means that you need to replace the coil of your chainsaw as it is malfunctioning.
