At the switch Boxes, what does the Black and Yellow Wire do?<br /><br />Is it supposed to get power from the switch and power the switch boxes, or is it supposed to ground the switch boxes/stator at the switch in the off possition.<br /><br />My switch I'm trying to wire in has 6 Posts,<br /><br />AM<br />B<br />M<br />I<br />S<br />C<br /><br />The AM is Ground I think.<br /><br />The B is Battery, got that part.<br /><br />The I stands for Ignition Circuit.<br /><br />The S is for the starter solenoid, got that part she cranks all day.<br /><br />The M is for the Magneto Circuit.<br /><br /><br />The harness I'm trying to wire in has these wires<br />Black<br />Red<br />Red/Yellow<br />Yellow/Black<br />Black/Yellow<br />There is also a purple, but it stops at the engine plug.<br /><br />The other wires are for the tilt/trim and I got them figured out.<br /><br />Here is what I have,<br /><br />AM to Black<br />B to Red<br />S to Red/Yellow<br />C to Yellow/Black<br /><br />Here is where I'm unclear, does the Black/Yellow go to <br /><br />M - Magneto , This seem to be ground when switch is on.<br /><br />or <br /><br />I - Ignition this seems to be Power when switch is on.<br /><br />I have tried it both ways, no spark either way, could I have fried something?<br /><br />Thanks<br /><br />Ben
