Abstract
A distributorless ignition coil has two high voltage secondary windings wound around a primary winding, with each secondary winding being electrically connected to a respective spark plug. A shield surrounds the secondary windings. The secondary windings share a common center tap between them, and the center tap is electrically connected to the shield, which thus acts as a conductor to convey current back to an end of the shield that conveniently may be connected to ignition components to complete the electrical path, thus obviating the need for an interior wire extending from the center tap inside the coil to the end of the coil case.
