ignition switch

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 on my omc iginition switch so i can hook the right wires to the right terminal and bypass the push in choke on the iginiton switch on my mercury control box

Re: ignition switch

Raised "M" (Magneto)=(Black/Yellow wire)<br /><br />Other "M" (Magneto) = Black<br /><br />Terminal "A" (Accessory) = Purple<br /><br />Terminal "C" (Choke) = Undetermined<br /><br />Terminal "S" (Starter Solenoid) = Undetermined<br /><br />I feel sure that you can figure the two undetermined wire colors.

Re: ignition switch

i'm not sure if this omc push in choke iginition switch will work on my 1979 mercury control box it is a older box the box has the choke button on it and 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, 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 /> 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 />so i'm not sure in where to put the wires<br /><br /><br />
