Stator questions...
Where to start first?
Did usual test battery, had to charge, test leads on showed voltage same as running as off.
So I moved to the plug on the voltage regulator and unplugged it and liquid came out of the plug? Normal?
And then checked AC voltage on the plug coming from the stator, 13 volts... So bike parked
Main question is does enough have to come off the bike to change to get access to the shaft seal? That expensive 1.99 part..

Shaft seal? Crank seal behind stator? Which is sprocket shaft seal. Need to take stator off. Or I would to make it easy. I did. But maybe you mean seal on wires coming out of primary for stator to volt reg????
What issues are you having?
13 volts if the bike is revved up is to low. Should be around 14.4 v volts DC. Should also go up to 80-100 volts AC when revving up bike, when measuring at stator plug. Around 20 v ac per 1000 rpm.
Seal on primary plug, is not replacable, on models I know.
Some say you can grind the primary enough to pull stator out. Which is how it should have come from factory. But also once you are that far, not that hrd to remove inner primary. And no risk of shavings.
Many people repalce with cycle electric
What year, model, and mileage?

It's an 01 Dyna and as far as I know it's the original stator.
Voltage at the battery didn't change running or off, so I dropped down to the regulator and when I unplugged it fluid ozzed from both plugs? Had to hit them with brake cleaner.. Before I could check the voltage out, and with bike running it only put out 10 volts... That's a wee bit low.
Oh back to you question, the milage is around 60 thousand..
I know the shaft seal was replaced long ago and it wasn't cheap except for the part! 2 dollars plus labor.. I think cams were cheaper to have installed than the seal

What you are calling shaft seal, I think is just seal on the case of the primary. Maybe looking at a manual or even parts diagram would help in the discussion here,
AC voltage should be about 80 volts when revved up high. If not, most likely bad stator. Not the plug, but the stator its over 20 years old with 60k miles. Replace it. By 60k, you got your money out of it. Despite the people who say mine lasted____.
What is your question?
I have an 01. They don't seal the that goes round the wires. They don;t sell the cable. They sell a stator as one piece. Just replaced mined at 87k due to age. Leaked for 10 years. Not water. Look at a manual and parts diagram. don't do this work without a manual.

It's common for older bikes to leak into the connector. Oil builds up in the wires and slowly leaks out..
Besides ac voltage at RPM, you need to verify that the stator is not shorted to ground.
In order to get the shift shaft seal, you'll need to pull the outer cover, comp, clutch and chain, and inner primary at that point and with the age it's best to replace all the seals in that area.

The grommet/seal on the wires is known for leaking. But to my knowledge, harley requires you to replace the stator.

The seal almost looks like a skate board bearing, think it the one that goes on the shaft going into the trans mission?
Going to be done a while.... Foot surgery comes first.

You mean on outside of primary on wires or shaft behind stator on engine?
Either way, I think you need to look at a manual
