[QUOTE="Kansas Bad Man, post: 50902, member: 778"] Greg is right on how a timing and mag function is changed by point gap change. A coil ignition also works the same way. [U][COLOR=#ffff00]T[/COLOR][/U]he coil is made up of a few turns of heavy copper wire [U][COLOR=#4dffff]w[/COLOR][/U]rap[U][COLOR=#80ff00]p[/COLOR][/U]ed around many turns of fine copper wire. [U]T[/U]he heavy winding is the low voltage or battery side of the coil. The amount of time the points are closed determines the saturation of the primary circuit. [U]W[/U]hen the points are opened the collapse of the magnetic field of flux crosses the secondary set of fine wire windings causing a high voltage of around 30,000 to 40,000 V for a very short duration of time. This high voltage is directed to ground at [U]the[/U] spark plug electrode causing spark. [U]T[/U]he points[COLOR=#ff0080],[/COLOR] when opened[COLOR=#00b300],[/COLOR] have a tendency [COLOR=#00b300]to[/COLOR] draw a spark as all electrical circuits do. A condenser or capacitor is employed to aid in the longevity of the points. [/QUOTE]
