Where does the voltage go in an ignition coil?
Depending on the type of coil you have, this voltage either travels from the single ignition coil into a distributor, from the coil itself into a spark plug wire, or in the case of Coil-On-Plug (COP) systems, the coil sits directly on top of the spark plug.
