Stator test on 1998 flhtcui
Not charging, battery has held 12.57 v for 3 days. Test both terminals from stator to reg at once with multimeter and individually shows l to jump to 2 or 3 then down to .2. Is stator bad?

Not sure if you noticed this nice how to thread:

"Set meter to lowest ohm scale, like 200 Ohms, typically. (Note: Not 200K ohms). Check resistance between the two stator plug pins. Should be fairly low. My Book says 0.2-0.4 ohms. The spec is in your shop manual. If it is infinity, stator is blown open - Replace. If it is 0, stator is shorted to itself – Replace. I hesitate to suggest the shorted to itself test, as the novice electrician with a cheap meter is likely to screw this up. Cheap meters may not be able to determine that low of a resistance, and the zero may not be correct on them. What you can do, if you want to put any faith in this (shorted to itself) test is to first touch your two meter leads together and note the reading. It could be 0, or 0.4 or even 1 or 2 ohms. Then when you test across the two stator pins, you should have whatever you just measured plus 0.2 to 0.4 ohms. So, a reading of 2 ohms with the leads shorted and 2.4 ohms with the leads on the stator is within the book’s spec. It is very rare for the stator to short to itself, so I wouldn’t worry about that one too much. Much more common for them to blow open or short to the case."
