I pulled my Stator cover to check it out. Looks ok? or No?

There's one black looking coil there but hard to tell if its bad or not
Did it pass or fail the isolation test?
You should really do voltage checks

Yeah, you can't tell if they're good by just looking at them. Most look a little burned up but work fine.

some are obviously burned up, some not. As stated, did it pass diagnostics?

I am fumbling through the voltage checks. I am no electronics wizard at all!

Going step by step in the stickie posted by DeCosse here is what I've found:

A ‘cold’ resistance check for shorted diode/SCR:
Unplug both input & output plugs from R/R;
With your meter set to read resistance (use a diode test if the your multi-meter has one), test from each pin of the three pin plug, to both the red & black wired pins of the 4-pin plug; NONE of these should read short circuit (zero resistance); depending which way you bias the test leads, you may get some reading (from the forward bias of the component) but it must absolutely not be a short. If you see a short on any of these readings the R/R is defective.

Set to 20M I got similar readings from all 3 plugs.
1.5 when connected to the Black
2.5 to 4.5 when connected to the Red


Next, do a resistance check on the stator (check at the cable connector going back towards the stator itself).
Measure between the three respective combinations of the three pins:
1-2
2-3
3-1
This time each of these should measure almost short circuit (very low resistance in order or about 1 ohm)

With my meter set at 200ohm I measured
.6 ohm
.6 ohm
.5 ohm


This next check is probably the simplest/quickest way of determining a stator problem - in majority of cases a bad stator will be indicated by failing following test:
Check resistance from any one pin to the engine ground terminal – this should not read any indication – maximum resistance or open-circuit.
If you read ‘short’ in that last test, then your stator is bad.
(if open, it is not quite guaranteed your stator is good however - but in majority of cases a failed stator will fail this isolation test)

In this test I got no reading in Ohms. Literally the Voltmeter didn't do anything.

Check the AC voltage output from the stator with engine running:
Leave stator disconnected from the R/R and start the engines.
With meter set to read AC Volts check
1-2
2-3
3-1
All three should be the same value – any significant difference of one reading will indicate a bad phase and the stator is probably defective.
At idle this should be ~ 20V* and rise to ~ 70V* at 5K rpm.
I hesitate to use absolute numbers here as this can be different between models and test equipment and especially the engine rpm!
What you are looking for is same value between phases and like increase on each phase as rpm increases.
If any of the above tests raises suspicion, pull the cover & inspect the stator. It is simple to do and can set your mind at ease by seeing what it looks like. Hopefully NOT with 1/3 of it a black charred mess!

In this test It didn't measure any volts at all on any configuration. The bike was cold and this was the first I started it up all day. Just double checked this again and still nothing.

Am I doing this right? Any helpful thoughts or reccomendations? Should I go ride her and come back and check things after they warm up?

For the last test, meter needs to be on AC volts, not DC

What does DC voltage measure across your battery when all connected up & bike is started up & running?

Thanks DEcosse! I remeasured in AC and am getting between 26-27 at idle. My voltmeter won't allow me to take my hands off to check with engine at 5000rpm.

DC voltage with the bike running is at 13.6-13.7

Where to look next or does something stand out as a problem?

Charging system is all working properly - you probably need a new battery
Recognize I believe you just changed it but does not seem to be charging sufficiently.

It just got changed about 2 maybe 3 weeks ago. I ride the bike almost every day and keep it on a tender every night. I just don't get it!

Yes. Heat the R/R up after an hour ride, then re-test.
