I've been asked about wiring alot recently. So here is a diagram that should help everyone. Let me know if you have any questions.

Heres a couple basic wiring diagrams i use :

5 PIN



You could wire a saftey tether in for the seat switch- then go right to the starter solenoid.



7 PIN




Again- setup could be changed a bit, if you wanted to run lights separate on thier own circuit- you can bypass the anti fire solenoid part as well .

I usually wire everything to a 5 PIN ign switch - but these two give different options.

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.

Do some engines have a charging system built in or do people need to put in a altornator

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
