5-1 DESCRIPTION
Engine performance and efficiencyto degree, governed by how the tuned specifications as determined by the designersThe work outlined in this must be performed in the sequence given and the Specifications listed in the AppendixT ignition system consists of primary and secondary circuitT low-voltage of the ignition system is the primary circuitP of the primary circuit include the ignition switch, ballast resistor, neutral-safety switch, primary winding of the ignition coil, points in the distributor, condenser, and the lowtension wiringT secondary the highvoltage surges from the ignition coil which in -high-voltage spark between the electrodes of spark plugThe seconda includes the secondary winding of the coil, coil- to-distributor high- tension lead, distributor rotor andignition cables, and the spark plugsWhen the points closed and the ignition switchfrom the from the flows through the primary winding of the coil, through the points groundT flowing through the primary winding of the coil magnetic field around the coil windings and energy stored in the coilNow, when the points opened by rotation of the distributorthe primary circuit is brokenT surge the as the points begin open, but the condenser absorbs the currentIn doing, the condenser break in the flow and rapid collapse of the field in the coilThis
