Power Arc Ignitions
Precision Performance for
1, 2, 3, 4, 6 & 8 Cylinder Engines

Power Arc's proprietary optical ignition systems offer extreme stability. A truly different product, you will notice a difference with this ignition.  The stability of the ignition helps to increase engine life and acceleration.  All ignitions are designed and manufactured in the U.S.A.


Two ignition models are available CD2-LM & CD4-LM. The number represents how many coil cores the ignition is capable of driving. The ignitions have four timing maps. The module is extremely small and requires no external box or case see dimension drawing here. The ignition can be programmed for use on selected motorcycles including Harley Davidson (Single/Dual Fire), Honda, Kawasaki, Norton, Royal Enfield, Triumph & Ural.  It can also be used on tractors, cars and other 1-8 cylinder engines. The CD2-LM and CD4-LM ignitions use interchangeable adapter plates allowing the ignition to fit almost any engine with an exposed cam or crank shaft.

Smart Point Modules
Smart Point Modules are designed to work with your existing points.  They can be used with either the MC-1 or MC-2 coil.  They can also be used in distributor based systems.  Click here for the Smart Point owners manual.

Features include:

Snap action output which provides high output. Improves starting on all engines especially if kick started
Automatic coil shutoff to prevent damage to the coil if the power is left on
Points draw virtually no current so they will last longer and will not pit or burn
Static timing light to allow for more precise and easier timing
High energy coil
6 Volt and positive ground versions available
