Re: Yamaha 115 2000 4 stroke won't charge
Most likely it's the rectifier & regulator. I have read a few posts about them failing on this motor. Yamaha has replaced the original part with the new one below.
the new Yamaha RECTIFIER & REGULATOR part is 67F-81960-11-00. It replaced the old one 67F-81960-00-00.
Does your batt gauge show 13-14 volts when the motor is running? what does it show when its off?
