This is a new Low-Tension coil that can be used on your hit and Miss Gas Engine with a normally open Ignitor. This is not for an engine with a “SPARKPLUG” or a “NORMALLY CLOSED IGNITOR”. Check your application before purchasing. This coil can also be used by a student for a Science Fair Project to demonstrate how electricity & magnetism work hand in hand and can’t work without the other. As any electrical device, this coil can produce a shock that can result in a reflex that may cause a person mild injury due to his/her reflex movement. We use Brass and Stainless hardware to hold the coil together. These materials are used because they are non-magnetic, so they won’t distort the magnetic field that is built up around the iron core, in turn giving a better uniform field that will collapse only around the windings when your ignitor points open. It has a 4-1/2″ Long by 2-1/2″ Wide footprint and is 2-3/4 tall. The shorter the coil is, better than long coils due to the fact the magnetic field is denser when the coil is energized. This will give you a more powerful induced spark. This coil is wound with constant tension on the 100% copper wire. Wood frame is made of solid Oak, connection terminals are Brass. The brass nuts are used to hold the terminals tight, and the nuts are countersunk to keep them out of sight, giving the coil a better appearance. The iron core was sprayed with an insulative material and allowed to dry before the first layer of wire was put on. This keeps the iron core from rusting. If allowed to rust, it will decrease the efficiency of any coil. Each layer of wire after that has a high temperature rated insulative material between them. All of our coils are tested before the outer cover and base are installed. With the wood base, it can easily be mounted onto a skid or a cart with or without a bracket.
