This is a Brain Tarp replacement for a single phase Kawasaki Part Number 21061-022.

This is a single phase rectifier for stators with 2 yellow wires out. This part will not fit on a 3 phase system with 3 yellow wires.

It has come to my attention that sellers are stealing my photos and using my text word for word. 
This is a real part. You will receive an identical rectifier to the one in the photo, and not a Chinese knock-off.
