How many windings are in an ignition coil?

An ignition coil typically has two sets of windings: the primary winding and the secondary winding. The primary winding usually consists of around 100 to 200 turns of wire, while the secondary winding can have anywhere from 10,000 to 45,000 turns. This high ratio of turns in the secondary winding is crucial for generating the high voltage needed to create a spark in the engine.
