Anyone have a wiring diagram for an M600?

I have the service manual, but the “wiring” diagram is a picture of the harness. I need a schematic that shows connections and components. I have to replace the ignition switch and repair the harness, and need to know what should connect to what. I have an old 600 with gas Wisconsin vf4 engine.
Any help is much appreciated.

Unfortunatly you will never get a *good* schematic. Bobcat will sell you a new harness and switch, but a wiring diagram... that will be hard to find, if possible at all. The electrics on these machines are very simple, any auto electrician could do the job if you don't think you can work it out.

Key on puts power to the + side of the coil, you may need to add a resistor to lower voltage prevent burning your points. Start on the key switch sends momentary power to the starter solinoid to crank the engine. Key off removes power from the + side of the coil and kills the engine.
This is how most old engines with points ignition and a battery powered coil work. (though I have no specific knowleged of that engine)
There really is not alot to it, any old school auto or small engine mechanic should be able to help you if you get stuck.

My problem is the connection from the starter key to the + side of the coil is broken, and I'm running a wire from the + coil straight to the + battery. This works, but I'd prefer to run it to that pole of the key switch, so that I can still turn off the engine with the key.
The maint manual diagram refers to the yellow wire, but mine are so old that you can tell the colors apart. Because the line is broken I can't buzz it through to check for continuity and find it that way. Hence, I thought I could find out which pole of the key switch this should connect to from a diagram.
Anyone which connectionon the keyswitch powers the coil?

As ken said, you just need those connections to the switch. You could run a new wire from the switch to the coil, and you will know its rite.
One thing to check, if your alternator isn't wired through a resistor, when you try and shut it down, it will not stop. As when the alternator is excited, it will keep producing power intill it stops spinning, even if you remove power to it. Its just one thing to keep an eye out for if you re-wire the switch and wonder why its not stoping.

Anyone know where the stock resitstor is on my M-600 and what it looks like? I should locate it and put it inline witht he wiring to the coil. Right now I got it running by going rfom the battery + to the Coil + with a toggle switch to allow me to kill the coil to stop the engine.
I don't want to burn out my coil or points. Can I get a resistor in Radio Shack for this and if so, what rating/ohms?
Thanks all.

First be sure that your coil doesn't already have a built in ballast resistor, many if not most are. If not the you can or at least should be able to get one from any auto parts store, just ask for a ballast resistor for a 70's Dodge car and wire it in ahead of the coil. They are white porcelon about 2“ long and 1/2-3/4“ in hight with a wire connected to either end. Wish I could be of more help, but unfortunately I'm not familiar with that machine.
