I have a Dixon 424 ZTR with a 11hp briggs and want to swap it out with a 15.5hp OHV briggs. Should be easy but the wiring. I know the two wires on the 11hp one is 12v ac runs the headlights and the other is12v dc charges the battery.

What's with the wires on the 15.5hp OHV. Searched everywhere no luck.

Help please
