What is a transformer and how does it work?   A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static solid state device, which insures, under normal operating conditions, a long and trouble-free life. It consists, in its simplest form, of two or more coils of insulated wire wound on a laminated steel core. When voltage is introduced to one coil, called the primary, it magnetizes the iron core. A voltage is then induced in the other coil, called the secondary or output coil. The change of voltage (or voltage ratio) between the primary and secondary depends on the turns ratio of the two coils.

Ignition system circuit: There are two types of ignition system circuit a.      Primary circuit. b.      Secondary circuit. Primary winding: There are three types of primary winding a.      Ignition switch b.      Primary winding c.       Cam distributor. Draw back contact point ignition system: 1.      Because of arching, pilting of contact breaker point system will lead to regular maintains. 2.      It requires maintained cause of moving parts. 3.      Because of inaccurate poor starting timing. 4.      Because of moving parts inertia its performance is poor at high engine.  Cam shaft speed is half of the crank shaft speed.
