Hi everyone
New to the forum, hoping to get some help with a 2007 GV250 carb version. Have had it for 2 years.
Was riding and dash lights and tach started acting weird. Tach was jumping turn signals blinking faster than normal.
Ran ok so rode home and turned it off to check things out.
Turned the ignition key on but nothing works no neutral light nothing at all.
Checked the battery, it was a little low 11.8 volts, but lights should still come on.
Checked main fuse but it was good, checked all the switches to make sure they were in the proper positions but nothing not that they ever stopped the lights in the past.
I don’t see any other fuses to check, started checking for loose connectors etc. but found nothing, any help would be greatly appreciated.
Thanks Hardy

Voltage is low but should light up, remove headlight & unplug the connectors & spray with contact cleaner replug everything & try again.

Hi Simon
So i just went over the bike again checking connections etc, but found nothing.
Had the battery on the charger but before I put it back in I checked for continuity between the neg and pos battery connectors and turned the key on and off showing that was working to get power. Put the battery back in but still nothing.
I decided to try the old push start and it started right away. However the lights on the dash kinda flickered so I started to tap the connectors and tried different controls horn, signals. I pulled in the front brake and the lights got brighter, disconnected that but no fix. Forgot to turn on fuel so it stalled, rolled the bike back to push start again and noticed the regulator was kinda warm when I sat on the bike because I had the seat off.
I think its hotter than it should be only running for about 5 min.
Will try to find test for the regulater.
Any shared wisdom would be appreciated.
Thanks Hardy

Hi Simon
Thanks for responding to my question.
Tried cleaning all the connections but still nothing.
Checked the harness connector red wire has battery voltage, orange wire has continuity to negative on battery so I’m thinking those are good
Checked ignition switch connector red and orange ohm out when key is in on position and the other two wires when key is in off position
Put the battery on a charger overnight and going to check some of the grounding points on the bike next.
Read a post somewhere (can’t remember where) but someone had the same issues and he said he was able to push start the bike and while running everything was normal again.
Doesn’t really make sense as it seems that somewhere in the ignition circuit there is something that is not allowing it to start normally.
However I will try that.
Thanks

You will need to report back the voltages you get from the stator unit @5k revs in AC , all 3 wires must have identical readings (hence it’s called a 3-Phase stator)
A stator that is about to give up the ghost tends to slowly fry electronics (anything that is attached to the harness, has an upper limit of how much “current” it can tolerate vs amps)
Regulator = Common, it if its Hyosung branded, don’t buy another one , they always fail since Hyosung doesn’t make them , it is an outsourced part , hence you probably won’t find OEM regs sold on this site. ebay is fully of fakes , especially those made in China/Taiwan are no better.
Also , when the bike is running, or battery is connected
- 3 Pin Plug for headlight must have 12v when you operate light controls
- fuse box will say 12v (without a fuse)
- Regulator connector will say 12v on the red & black wires (it is permanentely on , regardless if bike is OFF or ON)
(If bike sounds better with regulator and 3-Pin stator plug disconnected, you will need to consider replacing those 2 things, however it can’t run on battery , since even the lights want 55 watts from the stator unit alone) - pressing the Horn should have 12v , (horn removed)
Hope these tid bits help, keep us posted

Hi Guys
So the problem was solved.
Turned out it was the battery.
The battery was about a year old and the volt meter said 11-13 volts. Turned out it had little to no amperage, never ever have I checked the amps always went by volts.
Just goes to show your never to old to learn. ( feeling a little stupid)
Just wanna thank you guys for the quick responses and the advice.
Thanks again
Keep the shiny side up
Cheers Hardy
