Typical Ignition Coil
The carbureted B-2200 pick-up utilizes a standard-type ignition coil, constructed using the principle of mutual induction to step up low (battery) voltage
to high (ignition) voltage capable of firing the spark plugs. The coil consists of two windings of wire, primary and secondary, around a soft iron core.
When battery voltage flows through the outer, primary winding, a magnetic field is created. When current flow is stopped by the igniter interrupting the
ground connection, the magnetic field collapses onto the secondary windings, causing high voltage to be produced in the secondary windings. Ignition
wires then direct voltage to the spark plugs. The ratio of turns in the primary winding to turns in the secondary winding determines voltage
multiplication.
