what year is it.

Hyosungs have a reputations for destroying charging systems, inlcluding the reg/rec and the stator.

Aftermarket parts are available and more reliable than stock parts - electrosport sell a stator for an ex250 ninja that can be made to fit, and are much more reliable.

yeah, there are some easy tests you can do, get the bike running, rev it to 5krpm, and see what voltage you get at the battery - should be around 14v at 5000rpm.

You can also test across the 3 stator wires - unplug it, and test while running i think . . . will tell you what components are stuffed.

Especially with the hyosungs, once they stuff one component - they tend to stuff the whole system - i.e. the reg/reg fails - overcharges the battery and stuffs it, and also destroys the stator.

Do some tests, and if you are going to replace the reg / rec, or the stator, just do both, and add a new battery.

Then sell it.
