I picked up a mower and the wiring has been butchered. I need the basics set up again. My question is the 15hp briggs has 3 wires coming out of it. two come out together (red and black) beside the starter and use the same connector to connect to the mowers harness. Another wire (black) comes out beside the carb and the previous owner had a switch installed that grounded it to the frame to cut the engine off.
My thinking is the motor must be mag fired but have an alternator to charge the battery. The sole black wire must ground the mag for shut down. The two wires must be for the alternator but I don't know what they do. Perhaps the red feeds current to the battery when the engine is running. And the black? What do they do? As noted the wiring has been all cut up--essentially there is no harness for me to work with.
