I was just thinking and I'm not sure exactly what might be required when reverse engineering the OEM board or during development of the new board and software. To me it seems like running the two stroke engine. For using a scope or whatever might be required . It might be easier to build a sort of test stand.
I was thinking a shaft running in pillow blocks with a plate to mount the stator and possibly cutting the end off a bad crank and attaching it to the shaft in a way where different shafts could be mounted for testing with different flywheel and stator combos. The shaft could be turned by a motor with speed control. The shaft should be capable of turning between 1100 and 8000rpm to simulate engine rpms. The shaft could have a rpm sensor to ensure accurate rpm from the motor. I guess a circuit to be built to register signal normally sent to the coil to generate spark. Though I have no idea whether that is needed or how it would be accomplished.
I just figured that having the ability to run the ignition system on he bench rather than needing to run the actual motor for development/testing purposes would be a plus. Was thinking that being able to verify advance at specific rpms, test that the ignition doesn't lose accuracy over certain rpms, test operation of different circuit configurations, whatever and never needing to install test boards to an engine until a decently refined board is made would be nice.
One thing to work out would be making sure the motor is strong enough to turn with the power draw of the charge coils. I would say just disable the charge coils but some ignitions take power from those coils to operate. Others take power from the battery. I'm not sure which is the best solution.
I should be able to build the test stand with little trouble. I would of course be lost if it needs to pick up the spark signal and would need to google for the best way to setup the speed control, tach sensor, etc.
Either way, I may build this or a similar setup since it could come in handy for testing CDIs, stator coils, charge coils, etc. Giving me the ability to install these items with confidence they will work once installed.
I would love input about this idea whether to point out flaws in my thinking or make suggestions.
