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?

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!

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.

the techies have a screw option to replace the cut off sol. in their carb kits. not sure if briggs has the same thing or not. the plunger shuts the gas off when you turn the key off to eliminated that 10 second delayed pop from the muffler. if you have rewired for just the toggle kill and push button start, you could used a DPST toggle for the fuel stop solenoid. then you wont run the battery down trying to start it if you forget to turn on the other switch make sure to fuse the hot wire before the switch in case the wires or the switch shorts.

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.

Csonka39: Yes - the mag will have spark when its unhooked - you wont be able to shut it off until you touch the mag lead to ground tho.

Actually thats how i see if my clunkers i drag home work - unhook the motor from the harnesses ( to avoid a bad ign switch scenario) , and starter solenoid - just jump it off the starter motor - if it runs, then i hook stuff back up and troubleshoot from there.

I will say this, you dont always recieve a tractor with factory wiring...remember alot of us are CL hunters for free tractors..I just recently got a yard machine for my buddy's first off road mower...
lets just say, the guy said it wouldnt start......and I found out why...

12.5 B&S and it had some very strange wiring I hadnt seen before....mostly because it had a lot of rewirng to counter the auto shut offs and safeys..not to mention it didnt have a key, so that was "altered"

Its funny how things come full circle...I just posted a "typical wiring diagram for B&S" on my facebook...

@Fearless, I went back just to watch your video when you redid the craftsman...I too was confused, this 12.5 had two wires for the alternator..

I get mostly get questions on how to remove the saftey switches...seat, parking, and mower deck engagement...
