I followed the electrical fault charge on this website as well as the one from the maintenance book I purchased off ebay.
There are three wires coming off the stator; I've check their resistance (stator disconnected). Each of the 3 combination's has 1ohm resistance, so I assume the coils are intact.
If I check the resistance from each of the leads to the engine, there is also 1ohm, so I assume there is a short/grounding out. Test Phase B on the fault chart states, bad stator. I then took the bike apart and removed the stator, to confirm that the leads have 1 ohm continuity to the center metal portion of the stator.
I found a stator that matches my bike below, there are some pictures.

I had the seller test it and he get got the exact same results. 1ohm to center ground.
When the stator was on, I got 80AC 90AC 90AC at 5000 RPM. This is the last test from the maintenance book before moving on the the regulator/rectifier replacement.
I am really confused, is my stator bad and it's just a coincidence the *used* one on ebay exhibits the same readings; or am I not understanding the diagnostic procedure? Right now I am thinking that not only the stator is bad, but so is my RR is bad because it fails the diode test with OPEN either way.
Test phase C from the fault chart, I was also getting 12.5V .
The strange thing is, the bike will run just fine; I just have to keep charging the battery every couple days. If the battery dies and the bike is still running, I can still drive it as it will sustain itself until I turn it off.
Please help. Any suggestions would be greatly appreciated.
Richard.
