Thank you so much for making this tutorial. Just bought a second hand GV650 with a flat clock batt and now following your easy steps it works great. If anyone reading this is interested, I replaced it using a CR2032 3V battery and holder. Made the wires about 8 cm long which means it sits nicely on the lower right hand side of the speedo housing (not touching the electronics) once I put the circuit board back in, so next time no need to remove the circuit board as the battery is easily accessible.
The clock in my Hyosung GV650 has been keeping time for the past three months since swapping the battery. Previously it didn't hold time from the day I rolled it off the show room floor in 2012.... I assumed that's just how they were haha.
The original battery is the rechargeable one. I've switched it to a higher capacity. 1.5mah -> 20mah. Works fine, but time is delayed. within 12 hours in like 5 mins of the delay, every day. Don't know why. Might be a low charge on the battery so the time works much slower (?) and it affects the time that way. Mine is 2007 ver though
I (like many) had the battery die under warranty and asked them to change it. They replaced the whole dash and my kilometres were reset/lost lol. what idiots. About a year or two later it died again. I found a suitable solder-in replacement at RS Components but thought it might just be a better idea to recharge the existing battery. Was the one removed recoverable or are they just poo? Not sure I'd be super happy with a watch battery holder floating around in there but not a bad idea for somebody who doesn't like desoldering.
You definitely have to replace the battery you can't just recharge or or anything. When I pulled it all apart I saw I was not going to be able to get the new battery to stay on its own because it appeared to be spot welded to the metal clip holding it in and hence you want to put the watch battery holder in there. You probably could get it to stay somehow, but the holder makes it so much easier for next time. I agree something should be done to have it hold firmer inside the cluster though.
I'm looking at getting one of these bikes. The console already gets +12V so I'm going to modify the clock battery and use a 3V rechargeable battery and use a simple single transistor 3V DC->DC trickle charger on a bit of vero board. No more battery changes for me.
did you then make this change? if so, how did you do it? what pieces did you use? how did you connect? they are totally inogrante in electronics. Can you help me? :-(
My odo decided to put itself back to zero. Is this because of a battery issue? Someone on the Hyosung forum suggested this and I would have to replace it. How would I put the odo back to what it should be?
I don't think there is any way you could get the orginal number back, I remember mine reset a few times too and I think it is just an issue with the odometers in the bikes
Hey brother i had a question .. Is it possible to change the digital speedometer to an analog on this bike ? Coz I preffer analog coz its more reliable
I tried to do this for my 2007 GV650. The circuit board is a bit different though. It's not just a single board. There are two layers that are screwed together. The battery was glued in place, probably with a hot glue gun, or something like that. I probably could have gotten the battery off of the board, but I couldn't really see where I would solder the wires for my new 3V battery holder. I have no experience with electronics & soldering, so I just put everything back together. I'll have to live with the non-functioning clock until I can find someone who can show me what to do...
Update: I was able to get someone with some expert knowledge to solder a couple of wires for the battery holder onto the circuit board for me. Everything worked out just like it was supposed to.
