Stator issue

I purchased a new stator last year and just got around to putting it back on this year. I rode the bike for a little while but found that I am getting pretty crappy voltage. Around 12.5-13 in all RPM's. Here's the kicker -
1. I checked AC voltage between stator wires, all were around 60V at 3k RPM's
2. I checked stator wires to ground, continuity alarm went off for all of them.

It appears by stator is grounded, but it's still pushing out proper voltage? Not quite sure what to do at this point since it's basically a brand new stator with only about 8 hours of cruising on the bike so far.

Something isn't right.

Were the stator leads disconnected when you did the ground test?

Yes, the three yellow leads from the stator were disconnected and the bike off when testing ground. I tested against the metal of the engine and the negative battery terminal and both times it rang for continuity.

I'm almost positive the r/r is bad, so I just ordered a mosfet one off of eBay (used fz09 with the plug kit).

I rode for probably 2 hours today and the bikes voltage with bike off was 12.81V at beginning of day to 12.60 at the end.

I don't see how you got 60vac with all three legs shorted to ground though.

Yeah I'm honestly not sure. At first I thought it must be a mistake, but the alarm goes off right away from any of the three terminals. And I made sure the voltmeter was set to AC, and consistently got 50-60V when revving.

I'll try to get a video tomorrow to show it.

Try it on ohms setting also.

Okay, I was able to get a video of what's occurring with first continuity to ground, then ohms, then VAC output at 3k RPM.

It's exactly as you said, and still confusing about the continuity tone. I can't explain it, there may be some reason the audible can't be used. If all three legs had a path to ground, I don't think it would put out any AC volts or very little.

I was hoping to see the ground test with ohms instead of the audible, I wasn't clear on that. The norm is for the meter to show OL for open loop. As good as the other readings are, I would expect to see OL when using the ohms setting. If you get the OL on all three legs, your stator is perfect.

Ah, sorry about that! So I just tried using the ohm readings to go from stator wire to ground and they came up around 1.3-1.5 ohms.
