Re: ignition switch

Hope you haven't burned up your ignition system by putting 12 volts to it <br />red = battery<br />blk = grd<br />blk/yellow = ign<br />grey = tach<br />yellow/red = starter<br />yellow/blk = choke

Re: ignition switch

my control box has two push buttons on the side of it and 2 buttons on the throttle/ shift handle.<br />not sure what all the bottons are for and not sure if the inginition had a push in choke and there is <br />seems to be no warm up lever.<br /><br />the wirining harness to the control box has:<br /><br />yellow - going to the nuetural switch then to the old (new) ignition switch<br />brown - to tack / speedo <br />black - to switch then to tach / speedo<br />grey - to a button on the side off control <br />white - to the switch and to the same button as the grey<br />red - to switch<br />orange - switch<br /><br />the new switch is a push in choke and the letters on wiring terminals on the back of switch are:<br />B,M,A,C,S but has a bigger screw that has the letter M also that the old switch didn't have.<br />I have pics but I don't know how to put them on here tried to read how but do not understand

Re: ignition switch

That box is a older box for BATTERY POWERED CD the handle buttons are trim buttons one box button is trailer button the other is choke, you will have to do a little figureing what goes where, heres the original COLOR CODE,<br />red = battery<br />blk = grd<br />white = 12v power to ign, choke button and tach<br />yellow = start<br />gray = choke<br />brn = tach<br />orange stopped at the engine plug and didn't go any where<br />As far as the switch I wouldn't hazard a guess

Re: ignition switch

I have found away to view my 7 pics of the control box, old & new iginition switch. <br />Plus i would like to know is what does the letters by the wire terminals B,M,A,C,S but has a bigger screw that has the letter M also mean or stand for so i can hook the right wires to the right terminal and bypass the push in choke on the iginiton switch <br /><br /><br />
