MSD issue

spark in does not equal spark out if the rotor is not aligned (phased) with a spark tower at time of fire OR the cap button/rotor contact is broken. Align the rotor to a wire contact and scrape the white wire of the MSD onto a ground. You should get a false trigger from the white wire and a spark out the wire terminal your lined up with. Ive seen cap buttons shredded by the rotor if the cap is not clipped on 100%
