Reply To: Battery won’t charge on a GV125

[♠️ M77]

Hello,

Nice of you to get hands on with the bike, i encourage you to do more as most garages don’t even want to look at them despite being South Korean (not chinese! lol)

I would say you have stator and regulator issues as its not uncommon for any brand motorcycle to exhibit the symptoms you mentioned,.

Regulator = 100000%  (Very common on Hyosung as Hyosung used cheap outsourced ones , they didn’t make em)
Alas….
This would in turn annoy the stators (aka. alternators)

So if you don’t mind, please advise what year your bike is ?  Or are you able to drain oil carefully , and remove the stator and take pictures to show us.  Hyosung uses 3 different flywheels and stators in all of their GV125s even the new 2023 ones.   Can’t mix and match on this one.   Has to be exact or a total upgrade of the flywheel and stator as a 1 unit.

 

If you don’t mind me asking….

• Do you have heated grips ?  (Can be taxing as the 125 stators don’t like it, but can offer you recommended ways to keep your hands warm)
• Do you have USB charging kits near the battery for your GPS or Phones ?  (Check dodgy wires) could be sucking up the battery or taxing the bike when running
  (is it Oxford USB charging or some unknown chinese brand?)
• What battery do you have now ?   (eg.  YUASA  YTX 9BS)  (code names will be written on battery and the brand name)
• Are you handy with a multi meter ?  (aka, pocket tester)
