Model t spark coil wiring diagram. Wire 2 goes from the switch behind the fuel canister to bottom terminal of the coil. Each of these locations is logically separated by 22 5 degrees. When starting the model t engine on the magneto with the spark lever fully retarded the coil initially fires at 26 5 degrees. Indicated on flywheel drawing t 701 c.
This is a quick video showing how cool these early model t coils are and i show how to wire them up for use and give a demonstration of mine operating. The spark symbols show the points where the ignition coil will fire on the magneto current output with respect to piston travel. Each of these locations is logically separated by 22 5 degrees. So i thought i would modernize the ignition circuit diagram for the model t with this colour coded computer generated version.
Simplified diagram of model t ignition components author. The wiring goes as follows. Wire 1 goes from the frame of the bracket that holds the fuel tank to the negative terminal of one of the batteries. Credited with build commutator coil and wiring.
When starting the model t engine on the magneto with the spark lever fully retarded the coil initially fires. It also includes full colour coding for each of the wires.

Wire 3 goes from the igniter to lower terminal on the side of the coil.
