5+ Ways to Test an Ignition Coil with a Multimeter

An ignition coil is a crucial component of an internal combustion engine. The coil takes a low-voltage current from the battery and increases it to a high-voltage current that is required to create a spark in the spark plugs. Without a functioning ignition coil, the engine will not be able to start.

Testing an ignition coil with a multimeter involves measuring its primary and secondary resistance. The primary resistance is the resistance of the coil’s windings, while the secondary resistance is the resistance of the coil’s output terminal. The specifications for the primary and secondary resistance can be found in the vehicle’s service manual.
