I've been trying to get spark as the first step to starting my Grande. I've been checking the wiring, which has been creatively modified at some point in the past by humans and vermin. After discovering no voltage coming from the coil circuit, I jumpered it off the headlight circuit, (red wire to the blue wire) and got spark. Then got the fuel to flow thru the carb. Then used wire to get the muddobber's nest out of the exhaust pipe. And the damn thing started. I rode it around the block today and it seems to have good power. Anyone have an idea about what could be the issue with the coil circuit?
