King Horse 22 #1 Posted June 29, 2015 So I put new stuff on horse today. I also wired up a new Napa ignition switch. I noticed the voltage regulator is warm when the hot wire is hooked up. On another note before I put a new ignition switch on, the key was left on and coil starting smoking. Any ideas on what happened? Share this post Link to post Share on other sites
