Onan 4.0 BFA Electronic Ignition Bracket
thingiverse
The Onan 4.0 is a great genset. However, it can suffer from a bad case of points and condenser problems on the ignition system and parts are getting harder to find. There used to be a few electronic ignition kits available for this genset, however they don't make them anymore or at least I can't find them. I used an automotive kit that I drilled out the mounting rivets on to take the sensor off and designed this bracket to mount the sensor to this genset. Then it's just a matter of gluing a small magnet to the original breaker point. Pictures here: https://imgur.com/a/McYI5ko I recommend using ABS for this as the heat of the engine softens PLA. ABS will not hold up to grease, oil, and gasoline so this is for testing purposes only. I plan on having one of these machined from aluminum after I am satisfied with the design.
