What are you working on? A lot depends on what engine, what machine, and what setup you have. In particular, is the motor electronic ignition or condenser/points/magneto?

This is a repower? Does that have an external coil w/points or is it electronic ignition? I'm thinking the commands are electronic but without looking it up?? Does your switch have an M or an I term on it?

Another piece of info, I voltage tested the ignition start wire and when I turn the key I only get about .10 V. Is that normal? I'm guessing no
What are you calling the ignition start wire? Are we working on spark or cranking??

The S term on the switch should go to the solenoid for the starter and have 12v in crank. You will need a switch with an M term for the spark. Using one with an I will ruin the mag. I think there should be a tutorial on switches and basic wiring pinned somewhere

According to what I've read it's a CDI electronic ignition. Now does that mean it's magneto or ignition coil?
here's the diagram for the new engine. The wires i have from my switch are:
White - Lights
Blue - PTO
Red - Constant
Yellow - Switched
Black - Crank
Green - Goes to amperage meter
Other black cluster - ground
The only one that I can't find a place for is the yellow. If you compare my chassis wiring to above I have the following hooked up... in parentheses is the diagram notation :
Yellow - Not connected
Black - Starter tang (M)
Red - Main Solenoid Pole (N) Also has purple from regulator connected and main battery lead
Those three are the only switched connections that are left and i'm unsure of. The lights are connected and work in the acc position, the PTO works in acc, and on positions.
Does that help?

went out to the garage and pulled the switch out. I do have an "M" tang on it. That tang had yellow and blue coming out of it. Both of those have live power in Acc and On. The "G" tang is going to the white wire which is lights, The "A" tang is the red wire that is going to the main power lug on the solenoid, the "S" tang is the black wire that goes to the crank tang on the solenoid.

The S tang going to the starter is right. Look at F in the diagram. That shows a white wire going to the kill circuit at the switch term AI in the diagram. That should be the M tang. The M tang on the switch should have continuity to ground with the key off and show 0v and open with the key on. You should have a G tang on the switch that goes to ground.Do you have a B tang on the switch? That should be the main power wire that you have going to A. A is usually aux and it or L can be used for lights.
