Variomatic Posted May 10, 2017 Share Posted May 10, 2017 I need to know how to test a stator, the better on my bike isn't charging and am suspect theirs no output, or very little from the stator, and for the first time in two years my Haynes manual has let me down and left me confused. It has 3 outputwires, all white, anyone have any ideas as to how to test the windings? Do I look for continuity? Or measure the resistance? Is their a sequence to testingor do I just pick any two random wires outf the three? Any help at all would be appreciated Link to comment Share on other sites More sharing options...
finnerz89 Posted May 10, 2017 Share Posted May 10, 2017 Measure resistance between them all, you should get 3 identical readings. Also check each one for continuity down to earth (frame). Alternatively with the bike running you should get an AC voltage on each. Sent from my E6553 using Tapatalk Link to comment Share on other sites More sharing options...
Variomatic Posted May 10, 2017 Author Share Posted May 10, 2017 I just checked and they all have 1.1-1.2Ohms resistance, seems low but they're all consistent so it's probably ok, must be the rectifier Link to comment Share on other sites More sharing options...
Variomatic Posted May 10, 2017 Author Share Posted May 10, 2017 Update; Just checked my regulator, all diodes seem fine? Also checked the stator and it was only putting out 14v AC at idle? Seems low? Link to comment Share on other sites More sharing options...
finnerz89 Posted May 10, 2017 Share Posted May 10, 2017 Yeah that does seem low. What are the resistances like between the windings and the frame or engine casing? Sent from my E6553 using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my E6553 using Tapatalk Resistance between the windings seems to be 1-1.2 Ohms, which seems way, way to low to be, as far as I knew that should be closer to 50-65Ohms (I'll have a look in my Manual later to see if it says. Since when it revs up it puts out 12.5V (still anemic) it's JUST about enough to keep the battery charged and barely running, but you can tell it's not happy. I really don't wanna have to replace the stator, it's an oddly expensive part for the EFI model but I might have too Link to comment Share on other sites More sharing options...
finnerz89 Posted May 13, 2017 Share Posted May 13, 2017 You need to test the output from the stator though, if that's good then it will be the reg/rec or possibly the cabling in between the two Sent from my E6553 using Tapatalk Link to comment Share on other sites More sharing options...
