Hello, I have an '84 Evinrude 90HP V-4 that won't shut off with the key switch. Searches here have turned up information on a black an yellow wire that grounds out the ignition system. Could someone please elaborate on this system? Where does this wire originate and terminate? I assume it should have a good path to ground somewhere when the key switch is off, but I can't seem to find the wire at all. Any help would be appreciated, thanks!
