A coil builds voltage when the points are closed,this is called dwell,the time the coil 'soaks'and builds voltage to its rated value.this voltage is discharged when the points open,sending this "charge" to the spark plug.Any gaps jumped reduces this voltage,you cannot build voltage using discharge,only during the soak time the points are closed.
