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...
