   A riding mower engine you work on, sometimes has double, (2) alternators on the same plastic  ring. The black wire is not ground. 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. Briggs company had many different types of single alternators and also the common double red/Black alternators.   The wires plug connector hangs down behind the starter. 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.)
