Draw back contact point ignition system

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.
