Default Can you help me read my stator test? (w/pictures)

Can you confirm if this means my stator is shot, or if i'm an idiot who can't do this properly ?
i included the service manual page so can see for yourself.

I couldnt put all the pictures, but i tested the resistance between the 2 stator wires that are together, and between the 3 of them that are together (all combination and including a ground test through the frame of the bike which didn't show any current).
However number said .8 throughout the 3 wires combination tests, and that 193 number between the 2 wires.
seems like it should be max .55 for the 3 wires and online I foundout that testing for continuity between the 2 wires should probably give a umber close to zero. Is that right?

yes youre right the readings should be a max of 0.55 ohmns but I would expect a failed stator to give unbalanced readings either really high or low not the same on all three phases. Normally only one of the three coils fails and goes open circuit or shorts out with, frequently in the latter case, a low resistance to the frame.
I recommend carrying on with the other tests....

Give the guides in my sig a read through, they are very easy to follow and must be if an idiot like me can follow them HTH

i think your measuring the wrong connector. remove the 3 yellow wire plug that goes into the 3 white wires from the reg/rec and measure the ohm reading there.

just to remove some confusion: these picture are for the stator test, not the regulator test. I actually have a weird reading with the regulator test too, but didn't want to confuse the issue of this stator test reading. (plus I couldnt put up any more pictures).

Glang I am going to do just that: waiting on my new battery to test the stator while going up to 5000 as the service manual says (if I manage to turn the bike on!).I did test the shorts with the frame and that was normal (not showing any thing)

For the regulator (another test not pictured here) what what weird in my testing is that i get numbers in the 530s something (yes on the diode test, the one with the arrow) but also consistent across all 3, and nothing the other way (when I switch red and black probes to do the test again that way).

I think maybe I shot both stator and regulator. the battery was fried and the headlight fried too when the bike stopped working.

yup. but your reading the wrong connector. the 3 yellow wires that come out of the stator and go into the rec/reg are the ones you need to take a reading from before they go into the rec/reg. the ones you are taking a reading from at the moment are the DC side after the rec/reg.

look at the diagram it clearly states Y for ermm Yellow

Hey Geodude,so I used the samevideo for the regulator test! (not the test pictured in this thread) and i have a question: My reading is around 530-540 on all 3 (and nothing with the reverse red and black probes), while in this video the guy gets a reading of .490 so what does it mean? why is mine in the 500s when his is a decimal point?
(yes I made sure to be on the diode, the arrow, just like the guy in the video)

I did that (last picture and other pictures I couldnt post because it maxed out) and the reading came out at 0.8 on all 3 yellow wire combination. which is my question: does that mean it's shot?

the last picture is the correct reading (couldnt post all 3 pictures didnt have room). Those 3 yellow wires are the ones that feed alternating current created by the stator, to the regulator/rectifier which is why I tested them
