Ignition Coil Tech - Corvette Fever Magazine (1377 words)
First, let's consider what's inside a common coil: Coils have three posts - a large center tower, which is the connection for the secondary wire to the distributor cap and two smaller threaded posts for the primary wire connections.
The idea is to purchase a coil that is recommended by the manufacturer to work with your particular ignition system (according to Mallory, especially important with CD ignition systems), and today, one of the newest coil configurations you'll come across is the "E coil" assembly.
When a coil is designed to produce more current, the voltage output generally suffers, which taxes the ease of ionizing the gap.
