So I know this is an old thread, but this is the one I was using to test my stator so I figured I’d keep the info contained on here.
Here are two short questions I need answered:
1.) What happens physically to the stator that makes it stop working like it should??
2.) How does the stator reading as grounded to the engine mean it has failed? If you did the Tuxedo Mod isn’t the Stator grounded to the mod plate, and isn’t the mod plate grounded to the engine??
FOR THOSE WHO WANT TO READ THE LONG STORY: I did the tuxedo mod. Worked great for about 6 months of riding then it....uh...didn't work so great. Like a few others on here I had the bike fail to start suddenly, but after you scratch your head for a few minutes you go "man this feels an awful lot like when my stator went bad". Well I take the cover off and realized that yes indeed my stator was worn out. I don't know for how long but it had worn some grooves into the rotor, I was kind of in a hurry so I ordered a new stator and then I ordered the stator plate from GCExtreme because I figured the reason the failure occurred was because the holes I drilled in the plate I made 6 months ago were not quite perfect enough (even though I was pretty confident in my abilities) and the rotor was probably still fine.
Well I get the new plate and stator in and pray that my rotor will be fine…..this was not the case. Although it was charging the battery some it failed the first two tests on this list. Every leg said it had some resistance( see the confusion on my second question) and the VAC on each leg was around 27 at 3k RPM. That being said in my ignorance I still rode it for about 70 miles or so before it started to sputter like the battery was running low, and I got it back to the garage. I take out the stator and it now has grooves cut into one part of it and the wearing on the rotor has gotten so bad that the metal “laminate??” inside the rotor has started to peel at points. So obviously I am going to need a new rotor.
So this leads me back to my first question. What physically has to be wrong for a stator to fail? Is some of the deep wear around the outside edges where it rubbed the rotor means it is pretty much toast?? It is just a hard pill for me to swallow knowing this stator only has 70 some odd miles on it….
