I’ll be daring and give it a try. You have an alternate firing two cylinder with the coil from an opposed twin. Testing the coil is done like an opposed twin where you test across the plug leads if you have the flywheel off – not lead to ground like a normal alternate firing twin. When everything is working the brushes ground alternate sides of the coil. To do that on the underside of the flywheel is a bakelite disk for an insulator. There are grounding points in it. The brushes make contact on each side and provide the alternating spark. The brush holders have to be clean and provide insulation for the brushes and there has to be contact through the grounding points with the flywheel. Once everything is clean and correct magic happens.
Did that help any? Experts don’t be afraid to jump in here.
