have you been talking to jmech ?
please tell us how a point system works ...how it fires the coil

I suspect you're poking fun but since you asked, I actually know this from physics class. If you think I'm a bore just move on but I find it interesting.
When a wire passes through a magnetic field, electrical charges are forced along the wire as current. The high voltage coil has maybe 2000 times as many windings as the primary coil. The primary winding is energized by the battery like an electromagnet. When the points open, the magnetic field collapses, passing through the secondary coil windings, inducing high voltage across it. The ratio of primary to secondary windings dictates the magnitude of the voltage at the spark plug.
There are two rules that help explain the behavior of transformers, coils, motors, generators, etc. They are both strangely called the "right-hand" rule but they are different.
1: Make a fist and stick your thumb out. Your thumb points in the direction of current in a wire and your fingers wrap around the wire in the direction of the magnetic field around the wire.
2: Point your index finger like a gun in the direction of the magnetic field, your thumb straight up in the direction the wire moves through the field, and your middle finger straight out from your palm in the direction of current flow in the wire.
I could go on but I don't want to get banned.
