The spark plug is powered by electricity that runs through the ignition coil. The chain saw is powered by sparks from the spark plug and fuel from the engine. It’s easy to test the coil at home.
How does a ignition coil work?
When the key is turned on, a low voltage current from the battery goes through the primary winding of the ignition coil, through the breaker points and back to the battery. The magnetic field formed around the coil is caused by the current flow. The coil’s magnetic field collapses when this happens.
What would cause an ignition coil not to fire?
There are a few reasons for no spark, new coil pack could be faulty, crank sensor could be malfunctioning, or bad wire in the primary circuit. A good technician will be able to diagnose and estimate the repairs.
How do you test a chainsaw coil?
If you pull the start rope on the chainsaw, you can see the end of the plug. The chainsaw coil is good if you see a spark jumping between the plugs. The chainsaw coil needs to be replaced if there isn’t a spark.
How is an ignition coil constructed?
The iron core is surrounded by copper wire. The primary winding does not have a lot of heavy wire. The secondary winding is made up of thousands of turns of smaller wire that is insulated from the high voltages by a layer of oiled paper.
What wires go to the ignition coil?
The spark plug wire, the power wire and the ignition switch wire were usually required. The metal core and field coil windings make this coil heavier than a soda can.
How do you test an ignition coil with a multimeter?
One of the multimeter probes should be inserted into the center opening of the coil. The second probe of the meter should be touching the ground. The meter’s reading should be between 6,000 and 15,000. The coil’s secondary winding isn’t good if it doesn’t.
What should the Ohms be on a coil?
The level of electrical resistance can be measured using the ohms level. You can use a clearomizer between 2.4 and 2.8 if you have a regular level of ohms. This is the most common range chosen by those looking for replacement coil and 2.5 is the most popular.
What causes a weak spark on a chainsaw?
A weak spark on a chainsaw can be caused by a misfiring component. Most spark issues can be prevented with proper maintenance and cleaning of the saw. A few simple tools and parts can be used to fix most problems.
What gives the ignition coil power?
The battery has low voltages that can be used to power the ignition coil. The high voltages of the electricity are converted into high voltages by the coil. The distributor parts that cause the ignition coil to pulse are moved by that.
Can a bad ignition coil cause no spark?
If there is no spark, the problem may be caused by something in the ignition circuit. A bad coil or a cracked distributor cap can prevent the spark plugs from being fired.
