Spark ignition using points & condenser is a strange beast.
The coil is a transformer and generates the high voltage. The low voltage winding of the coil is connected to the + and - terminals. The high voltage winding goes to the terminal on the top and the - terminal. It does NOT go to the case of the coil. So ask yourself - how does the spark energy get from the spark plug back to the - terminal? The answer is: Through the condenser! It can't go through the points as the points are open.
Please don't ask me to explain electronic ignition.
