Did oil change n other misc items..
I always check charging at battery when looking a bike over. Bike wasn't charging so did typical tests n found bad stator..
Replaced stator n reg w oem.. Here's where it gets weird n I'm lost now..
Stator unplugged n it puts out 60+ ACV all day long..
Plugged in n it drops to 11 ACV n only 12.4v or so at battery..
I've spent a month or more trying to find the problem..
I've used 3 different regs now (OEM twice n a cheap Chinese) , I used a 4th one that is the mosfet type to bypass all factory wiring.. They all do the same thing.
I've pulled the stator n checked for pinched wires etc.. All perfect.. All ohms tests are perfect for stator , all wires to/from reg to battery ohm out perfect. Grounds are good, no burned plugs, battery voltage at red wires on starter relay.. Unplugged at reg gives me 60+ACV, battery voltage at unplugged reg...
Only additional load are two lights up front..
So two key points ..
Lose ACV plugged into stator
Lose ACV plugged into reg
If I unplug either its good
Wiggling wire harness n plugs no change..
I'm n 04 MMI grad . been self employed for many years. (Normal day job plus working on bikes at home, now 4 yrs just working on bikes)
Any n all ideas appreciated
