Model T Spark Coil Wiring Diagram
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.
Model t spark coil wiring diagram. When starting the model t engine on the magneto with the spark lever fully retarded the coil initially fires. Henley publishing co ny 1917 p. Ful internal combustion engine used something like it in his engines as early as 1862 2 the jump spark system employed a spark. Each of these locations is logically separated by 22 5 degrees.
The wiring goes as follows. Each of these locations is logically separated by 22 5 degrees. Wire 1 goes from the frame of the bracket that holds the fuel tank to the negative terminal of one of the batteries. One thing i failed to address in the video.
So i thought i would modernize the ignition circuit diagram for the model t with this colour coded computer generated version. The spark symbols show the points where the ignition coil will fire on the magneto current output with respect to piston travel. Feel free to download and print for your own reference. 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. The spark symbols show the points where the ignition coil will fire on the magneto current output with respect to piston travel. Simplified diagram of model t ignition components author. It also includes full colour coding for each of the wires.
Wire 2 goes from the switch behind the fuel canister to bottom terminal of the coil.
