skyap Posted February 14, 2020 Share Posted February 14, 2020 Hello all, new here! I've had a yamaha YBR 125 Custom for a few years now. I used to ride it most days to work but a couple of months ago it stopped turning on. I checked the switch barrel and contacts seem ok. The kick doesn't do anything. No lights come on. I tried to charge the battery with my car but that did nothing. I eventually got someone to collect it and fix it and he said a fuse was blown! So I rode it home again. A week later I went to ride it and it was back to being dead. Could the fuse have gone again or is it more likely to be a dead battery? This time when I used the kick the neutral light flashed on for a split second but then nothing. If the battery is gone, do I just need to order a new one or should I get a charger of some sort to charge this one? I can be hands on and don't mind doing the work myself, I just don't know much about motorbikes yet! Any help is appreciated. Link to comment Share on other sites More sharing options...
neversaydie Posted February 15, 2020 Share Posted February 15, 2020 Yes, the fuse may have gone again, particularly if the cause of the fuse blowing originally hasnt been repaired. If it has, you need to find the fault. Likely to be a short or bad connection somewhere. Then charge the battery and see it it holds up Link to comment Share on other sites More sharing options...

skyap Posted February 16, 2020 Author Share Posted February 16, 2020 I replaced the fuse but as I plugged it in there was a large spark between the bit of chrome above the horn buzzer and the engine block! Nothing turns on and I'm pretty sure the fuse has blown again. What's the best way to find the electrical fault? Or is there anything obvious?

jimmy Posted February 16, 2020 Share Posted February 16, 2020 If there was a large spark, there will be some scorch marks from the arcing. Look for any wires with the insulation cracked , or bare wires touching the horn or engine I'm assuming you hadn't carried out any work immediately before the problem started. If you had, then look around the area you were working on. 1 Link to comment Share on other sites More sharing options...
