alternator/battery/charging related problem
So i was leaving work late last night. As usual, i warmed the bike for a few minutes, everything looks fine so far. I jumped onto the bike, and as soon as I rev it up in the first gear, the headlight went off. I rode for another 10 seconds to see if the light came back. No luck, so I stopped, turned off the bike and checked the connection. Everything looks secured.
Tried to start again, turned key to "ON" position, no lights were on, I couldn't start it. However, as soon as I push the bike, the lights on the dash came back and went off if the bike stopped. I was able to get it running again by pushing start. I rode it for a minute, the headlight kept flickering, and went off if I didn't give gas. After that minute, headlight stayed on. I was able to ride it home without any problems after that. Any ideas what causing this issue? I am thinking it's more like grounding or charging related problem. Oh, the bike is a 08 Kawi 250R. Sorry about the long read, thanks. |

Also note that the tachometer was acting weird at that time. The RPM was jumping up and down like crazy as it's very unstable and not accurate.

sure sounds like a wiring problem... either chaffed insulation allowing bare wires to touch, loose connector or a bad ground.
been working on the bike lately, just prior? |

i had a similar problem on a previously owned interceptor. both headlight AND erratic tach readings were eventually traced to a bad spark unit. this may be useless information as i am not sure what would be the equivalent on your bike.

i finally had a chance to look at the battery yesterday, it turned out that the screw that holds down the down positive terminal was loose. The screw almost fell from the top when I removed the seat. Tightened it and rode for another half hour with no problem. Hopefully that's the reason why the bike was acting weird. Thanks for all the advices.
