Thats awsome! Tis will come in handy alot for me! I want to rewire the craftsman, but keep the key switch. This will save me some guess work!

I had a different diagram one for the twin wire off the stator - but the wires wouldnt match the ign switch . These are also the clearest/sharpest copies i could find as well ( plus color coded).
Usually, the way it works is L ( and the white wire off the stator) is for lights - G is ground, B is battery and S is start ( starter solenoid) - Y or M is for the saftey circuit/ shut down from the magneto.
Ill usually run the 5 PIN switch as i mentioned- its easier to wire and sometimes ill either run separate switch /power to the lights off the battery , and a separate kill switch as well.
Years ago i somehow found a site that had all these different wiring diagrams for murray tractors- i printed out every one - i have a folder for all the wiring diagrams and parts lists for some of my fav tractors.

Most lawn tractors have an chraging circuit under the coil, with two wires coming from them. These can go bad though, best way is to check it with a voltmeter, you should be producing about 12-14v at full rpm, and about 6v or so at idle.
Im planning on running a 30a car alternator to run halogen lights and a winch on my mudder.

Yepper- older motors that use a generator dont have the stator , push mowers w/o electric start dont, ive got a 70 toro with a 5HP electric/ pull start motor that doesnt have a stator - it originally had a lil plug in the side where youd plug it in the wall to charge the battery ( that part is gone now).
After engine manufacturers quit using generators, they went to a one wire stator( just to charge the battery) , now a days its two wires- one charges the battery, the other wire runs the headlights. Some tractors have an external voltage regulator under the dash - those are usually heavy duty garden tractors with multiple power acessories.

I beleieve the red goes to the +ve of the battery, as this is what charges it, and the black is to run lights etc from. Dont quote me on this, dangeroustoys will have a better idea.

Sorry for bringing this thread back from the dead, but I am having a problem directly related to this thread. What do I do with the black wire if my tractor does not have lights?

the wires are usually painted black, use some sand paper or a craft knife to scrape away the paint. The red wire charges the battery, and the orange or white wire is for the head lamps

What if I have no headlamps? Wouldn't that not complete the circuit?

ok so what if i have the carb with a wire coming out of it? i need to put that engine in another tractor and i cant take the wire harness with it because the safety switches wont work on the new tractor
i have wired a few tractors myself and they always work out for me i just need to know what to do with that wire

Your carb has a fuel shutoff solenoid. You can bypass it by unscrewing it from the bottom of the float and snipping off the needle that you see. You will need to use a manual shutoff on the fuel line after doing this though. Refer to my video if need be. Good luck!

have you tested this out yet? because its actually my brother engine that has it and i dont wanna have to pay to fix it for him if i do something wrong, and he actually runs the manual shut off anyway because if the fuel is left on it floods the engine

I have an engine with that electric valve on it in my murray. I ran it to a toggle switch as a sort of secondary cutoff along with the coil wire. I can't remember how I wired it in though.

i have a spare carb for the engine anyway so i just cut the plunger off and the engine runs fine, no problems at all so i put the engine on the other tractor and wired it like i normally do and it runs great

First of all, Thanks for response. Correction, I have a 16 hp twin briggs pig, ordered a new coil as the one the motor had was burnt at the ground and wires where coming from inside the plastic. So, technically once i install and gap the new coil w/ the ground unattached the motor should give me some spark, correct?, from there I can bypass wiring like the diagram from fearlessfront, and be set to dominate the back 1/2 acre.

I've had good luck wiring up a couple of my mowers, including a twin, using the diagram posted by fearlessfront. It's in the wiring topic stickied to the top.
