i have accumulated a certain amount of wiring knowhow over the years on tractors and lawnmowers... one question, my 15.5hp Briggs has TWO harnesses coming out by starter. one w/red/blk ... the other (not sure of wire color) i get that one black wire is more than likely the kill wire, and the red i'm assuming is the battery charge wire... and the (yellow i think) may be headlight feed...which leaves the 4th wire? i may have to pull flywheel to see for myself.... or is the 4th a ground for the headlights?
