2010 m8 with 4000mi no spark. I have found some great info on here but I'm still stumped. Sled was running good before this happened, it was like someone was hitting.the kill switch. Kept happening more frequently til it would not start. So far I have disconected the key, kill switch and tail light. Still no spark. It did get driven with a broken pull start for 2 days prior but I find it hard to beleive that it messed up the stator. There was rope dust in there but nothing grenaded. I turned off the lights in the garage and pulled on it and all the lights come on. Does this mean my sled is making electicity? I also tested what I beleived to be the stator coil resistance and got 0 ohms for both. Anyone got any ideas?
