Optimum wire length
More wire generates differences in voltage, and in turn extra pressure, that can cause the breakdown of insulation and wire coatings. So, we tightly control the length of wire between adjacent primary and secondary windings. The result? Our secondary winding is thinner and much longer than the primary in order to get the output needed for the voltage to jump the spark plug gap.
Smart processes
Ignition coil windings should also be evenly distributed and neatly wrapped. That’s why we wind both primary and secondary coils as smoothly and tightly as possible, directly onto a proprietary steel core. This approach helps to ensure maximum magnetic power in every turn of the wire. We also wind our secondary coils into more bays than many of our competitors for more consistent voltage distribution and reliable coil performance.
High quality components
We only ever use high-quality wires, and coating that resists the cracks, pin holes and imperfections that might cause other ignition coils to fail. A special Epoxy helps insulate these wires and keeps them separated. Gaps in the epoxy can reduce the integrity of the insulation, so we also employ a special vacuum technique to remove air bubbles and imperfections, and help prevent internal arching and shorts.

Resource Highlights
How does the design of ignition coils differ?
The design of an ignition coil can range from 2 to 7 pins and everything in between. Also, they could be single coils or multiple, molded into a single housing.
Does the design of an ignition coil affect how you test it?
For multiple coils molded into a single housing, you need to use a testing wand. This will pick up the back EMF during operation and send to the oscilloscope for you to review. This will help you identify which coil is causing the problem.
Do I need to test the primary side as well as the secondary?
Before you test the ignition coils, it’s a good idea to check that the primary 12 volt circuit is functioning properly. This is to confirm that the ignition coil has supply voltage and is working correctly.
