Folks have asked what the letters on the back of their ignition switch stand for. I found this and thought I would add it in here for those looking for this info:
M = Magneto
S = Starter Solenoid
L = Lights
A = Accessory
B = Battery
G = Ground
I = Ignition
R = Regulator/Rectifier

There are basically 2 types of switches and interchanging them can have bad results. If it has the I for ignition the switch will put 12 volts on that terminal. If it has the M for magneto it will gound that terminal to kill the engine. If you get the two confused and put 12v to a solid state ignition you will let the smoke out!!

Very true, Doug! Thanks for pointing that out. I don't have anything with that type ignition. And most switches don't have all those letters on them.
