What would cause a stator to only read 2 volts AC?
It's not shorted to ground and the resistance between the legs is good.

 

Assuming it is an old two wire single phase system. What is the resistance reading you are getting? Is it possible a few magnets have come lose and gone together or would that make max distruction?
Probably the connection is bad where the leads attach to coils. Reads OK till it tries to push the AC thru.

 

0.3 ohms resistance between the legs.

 

Good thought on the magnets.. The ohms seem OK for the stator... but... Failures occur of all Kinds...
matters not...gotta come apart anyway...
Double check yer meter...

 

At what RPM?

 

Were you having charging problems; the reason for the check?

 

2 different meters same reading.

Not sure bike doesn't have a tach.

Yep not charging.

 

If the magnets have slipped and come together you will not get alternating current on a sine wave therefore it will not put out any AC.... I am more suspect to believe a rotor issue.. This is your 3 phase setup right? And all phases come in at .3 ohm and infinite to ground?

 

Pull your derby cover and do the smell check. Betting that your stator is grounded, and hopefully you caught it early enough to save the regulator. Good luck.

 

They can be shorted internally. Or perhaps magnets. In any case, it's coming apart, so just do it.
