Re: What does an ignition module do?
It basically magnifies the signal of the pick-up coil.
Dwell with points is the time measured in degrees, like dave said, the points are closed. The satuation time that dave mentioned. The longer this time, the more energy the coil can build. The higher the engine speed the less time the coil has to build this energy. Back with points, a condenser was used to store extra energy. A coil fires when the primary current flow is disrupted. Electricity don't like to stop once flowing. So disrupt the flow by breaking the circuit with points or module the primary current looks for a new place to go. The secondary windings in the coil. These are of finer windings and many more windings then the primary windings. This amplifies the current enough to fire the plug. The secondary windings are wrapped around by the primary windings in the coil. Someone smarter then I will have to explain exactly how the current is transfered.
