msd 6al no spark at plugs

Got another battery? Even a small 12V battery from a kids ride along or a scooter can power the MSD. Its about 1A draw per 1000 RPM if my memory serves me correctly. Even a battery charger could power the MSD seperately. MSD takes min 10V to work. I too am trying to figure your toggle switch between battery and MSD/Starter button. Id rewire that and run the MSD fat lead straight to battery and toggle the small red wire. If you kill the small red power to MSD youll turn it off.
