I have a 1975 evinrude 25 hp outboard w/electric start that I am looking to have some help in wiring the switch. I replaced my keyswitch with a new choke in switch type switch. I now turn the key to start. Works great, push to choke, Works great, Turn off the switch, motor stays running. I am assuming that I need to ground the switch out some how. I need help on which lead should I use to ground the switch out when the key is turned off.<br /><br />these are the wires that I have with my harness.<br /><br />red=choke<br />white=solenoid<br />black x2, to coil<br />green,battery
