Drop Kirk a line and see if this works on the Onan. I love his stuff and have used it on my 120 and my 312.
Trandenser II Electronic Ignition System
Due to the miniaturization of transistorized circuits of high current capability, a complete electronic ignition system can now be made to fit in an enclosure no bigger than a conventional ignition capacitor! The Trandenser II is designed using IGBT (Insulated Gate Bipolar Transistor) technology to offer an unparalleled ignition performance upgrade to your Kohler or Onan engine that employs a battery-breaker point ignition system. The Trandenser II replaces the condenser, installing into the original condenser clamp. Breaker point current is reduced from 2 amps down to 150 milliamps allowing points to last virtually the life of the engine. The rapid switching capability of IGBT technology allows for greater energy delivered to the spark plug. The result is a system offering improved all-weather starting, vastly extended breaker point life, improved running quality throughout the engine operational range, and is packaged such that installation is a breeze! An integral LED static timing light provides a simple way of setting ignition timing precisely.
IGBT circuits have been developed for, and are widely used in the automotive field for ignition systems and fuel injector drivers. For those interested in this technology, see http://www.ti.com/li...169/slua169.pdf for a thorough technical description.
The Trandenser II module is designed to work with 12 volt ignition coils that have a primary resistance of 3.0 to 6.0 ohms. Most all of the stock ignition coils fall into this range. If your coil is an aftermarket replacement or uses an external ballast resistor as some Onan systems do, check primary resistance by measuring across the (+) and (-) terminals of the coil using an ohm meter. The use of aftermarket coils with resistance values lower than 3.0 ohms will cause the module to fail. Be safe - if in doubt, check before ordering. The Trandenser II is fully compatible with all of the ignition coils that we sell.
We are proud to offer this cutting-edge ignition system technology at a very reasonable price and with an unconditional 1-year warranty.
