Hi Jared, the wire is probably the alternator wire, don't worry about it at the moment, probably doesn't work anyway. As for the starter stalling, does the motor turn over by hand ? are the wires on the battery and to the starter motor and the earth wire to the frame good and tight so they have a good connection? are you testing it through the solonoid is this working ok? Are you trying to start it with the cutter deck engaged?
