FZ6 / Fazer / battery not charging
« on: 06 October 2014, 09:09:35 pm »
hi all , hope someone can help , had fazer for last 6 months with no fault, however last month the battery went flat, so as not knowing when it was last replaced i put a new one on. hey presto (i thought), a few days later , guess what sluggish starting. so i have a contact at yamaha, who told me that rectifier was very common , so £130 later i still have same fault. now I'm in the motor trade , but worked on cars for last 25 years , so i thought id check a bit further with the help of a multi meter , haynes manual & you tube. have checked stator outputs on 3 phases , I'm getting around 20v ac on all 3 at idle rising to around 65-70v at 5000 rpm. have checked resistance on all 3 and getting about0.6 ohm. & nice checked any dead shorts to earth, which there are not. finally I've checked earths ,
only ad ons i have are heater grips ( which I've disconnected ) plus wiring mod to utilise 2nd head lamp, but even disconnected that.
also forgot to mention that with meter on battery @5000 rpm it struggled to get 12.8 volts. and at idle 12v
thanks hope that makes sense
