I am thinking about using a universal start switch for my old fastwin. How would I wire it up it has BISA for markings I think that would be battery,ignition,start,and assy. my old switch had SSMM two start and two magneto. Any help would be great.

Re: universal starter switch?

You just get a new universal outboard switch. Get the push to choke if you've got an electric choke and want to combine that in the keyswitch too. Modern outboards work by grounding out a kill switch wire. So you use the ground and kill switch terminals on the keyswitch for each magneto line. They still label these two terminals 'M' for magneto.<br /><br />So your typical switch is labeled:<br />B - this goes to +12v on the battery. Probably one of your original S terminals leads here.<br />A - Accessories, things you want to get power when the boat is 'on'. About 15A max depending on the switch.<br />C - Choke, goes to the electric choke. Only on "Push To Choke" switches.<br />S - Start, goes to small solenoid terminal. Probably on one of your original S terminals.<br />M - Magneto, use one of your M lines.<br />M (Sometimes big or otherwise idenitified) - Magneto, goes to your other M line.<br /><br />Simple, huh? The important thing is to get a switch made for an outboard, since inboards and other systems usually supply +12v to the ignition system, which you really don't want to do.
