Model T Spark Coil Wiring Diagram
Feel free to download and print for your own reference.
Model t spark coil wiring diagram. So i thought i would modernize the ignition circuit diagram for the model t with this colour coded computer generated version. 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. When starting the model t engine on the magneto with the spark lever fully retarded the coil initially fires.
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. Wire 3 goes from the igniter to lower terminal on the side of the coil. 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.
Each of these locations is logically separated by 22 5 degrees. One thing i failed to address in the video. 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.
When starting the model t engine on the magneto with the spark lever fully retarded the coil initially fires at 26 5 degrees. Illustration from victor pagethe model t ford car ing the first success 1917 edition norman w. Wire 2 goes from the switch behind the fuel canister to bottom terminal of the coil. It also includes full colour coding for each of the wires.
