Great original equipment regulator/rectifier removed from a 2019 DR-Z400S with 3000 miles that was modified for adventure riding on the Trans American Trail. More amps were needed for charging the starter battery, phone, GoPro batteries, GPS, and camping lamps/bug zapper. This one is a perfect replacement for your bad regulator if you are keeping the bike stock. Fits many Suzuki DRZ and ATC models. Use barrel connectors to tie into your existing yellow AC connections. Red wire is B+. Black wire is B-. A flying lead with mating plug is included if you need to wire into the 3 yellow stator leads for a non-standard application. If your ATV has a single connector shown in the last photo, add spade terminals to the red and black leads, and plug them into your original plug. Slide the yellow leads out of the 3 position plug, and into the back of your 5 position plug as shown. Yellow leads have no polarity so they can go in any order.
