Thanks Mark you get rid of all of it. cap off any wires coming from the ignition switch that go to the stator. yellow wire to bat terminal on alt, white wire goes to single terminal on top of alt, green wire really not used but goes to "Alt" dash light. of course, run the 4ga battery cable to the battery. 1 Shep69 reacted to this Quote Share this post Link to post Share on other sites
