Help sourcing stator / generator in the UK
« on: February 17, 2018, 08:40:49 PM »

Hi all, after a period of 12 months since the last replacement my stator has failed again meaning the battery is not charging properly. Only about 12.5 volts generated when running. I have a fancy mosfet rectifier fitted and upgraded wiring loom to the battery. I have checked the stator and seem to have continuity between all 3 coils and the frame of the bike. This leads me to believe the stator has failed.

I do not want to fit another Hyosung stator again based on the very short lifespan of the last one. I understand a Ninja 250 one can be fitted? Can anybody point me in the right direction as to a supplier in the UK?

Thanks

Munky.

Have you checked the stator output?
Should be circa 65v between phases @ 5000rpm. Best to check its deffo dead first.

Cheers Sid, I need to get the wife to hold the throttle open whist I take the readings. The leak of voltage to earth was enough for me to suspect that part. That and it's the only bit of Hyosung left in the charging system!

Can anyone verify this is the correct Ninja stator

It's the same one I linked to above buddy.
Fairly sure it's correct.

I got the voltage tested it was about 60 v, 60 v and 2 volt. I suspect one of the windings has shorted to earth.

I'll wait until tomorrow so see if anyone has any other suggestions then place an order for the part listed.

If you have 60/60 and 2, then a winding is deffo down mate. Should be pretty much equal across all three.

Job done, I can confirm the 1997 Ninja 250 stator fits and works. I owe Mr Krainium a beer for that one. I had my doubts it would fit as the Ninja item is so much slimmer and the width tolerances are so precise a mm to wide and it would not fit.

Worryingly there was a lot of metal floating about in the generator case when I opened it up. It appears that the flywheel has been meeting the stator casing. I suspect this metal lead to the short lifespan of the stator. I checked the flywheel for freeplay and found none.  I have made a new gasket out of the thickest material in my gasket set, looks like 1.5 mm, I'm hoping this thicker gasket will prevent the flywheel and casing meeting again! Crossed my fingers and shoved it all back together.

All swapped out after work ready for the commute tomorrow.  Thanks to the forum information like this alternative part which means I don't have to catch the bus to work.

Congrats on not having to be stabbed by ice junkies on the bus munky!
