The other 2 end ground wires attach underneath ring to chassis top of engine. The two color wires Red+ Blk are (2) hot wires as output. A burned out wire would be only one red wire alternator burned out. A new diode put on other black wire wold be the new alternator as output. The flywheel can just stay on engine. The 2 curves of wound wires are on each side of plastic ring, 180 degrees and 180 degrees as completely separate. The wire plug connector hangs down behind the starter motor. Briggs company had many different types of single alternators and also the common double red/Black alternators. 4 amp output from red wire + 5 amp output from black wire. Most people don't use the headlights on riding mower that uses power from the black wire. The Briggs company was wrong using a black colored wire on factory assembly line. (Mechanics in general assume a black wire means ground.)
