Ed Gervasi 0 #1 Posted October 20, 2020 Folks; I purchased a 520H and see it is not charging. As I look at the harness and talked to a friend with several WH tractors. I look at my harness and see from the 9 pin connector, the yellow wire on the dash side is connected to a red wire and it connects to the center post of the regulator I just paid $60 from Onan. Now I have several questions . Where does the red wire go to from the center of the regulator. As of now as I said it goes to the yellow wire on the 9-pin connector. Where does the yellow wire goes to the 30A fuse and the tach regulator . God knows where this located is and what it looks like. My tachometer does not work and am wondering if this is related.
