Hello, I'm trying to replace some of the 30+ yr. old electrics on my 77 with some more modern stuff. The safety relay get's energized from the yellow wire comming from the stator. This current isn't really true AC or Dc from what I understand so I'm not sure what kind of relay to replace it with. The bike isn't running right now so I don't even know how many volts the yellow wire has with the bike running. Any help would be appreciated.
