How do you check a chainsaw coil with a multimeter?

Locate the coil on your chainsaw. Connect the negative and positive cords of the multimeter to the negative and the positive terminals of the coil in your chainsaw and measure the resistance. A brief answer is convenient for those who are short of time but it will not give you the necessary details of the matter.

How many ohms should a ignition coil have?

A typical value would read 0.4 – 2 ohms.

How do you troubleshoot an ignition coil?

What should ignition coil read?

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.
