Hello, I have the problem that my Yamaha scooter has already burned through the 2nd light bulb within 2 thousand kilometers. It is a 12V 25W light bulb. I used to measure with the multimeter at the frame of the bin and be able to measure almost full throttle around the 15-16V volts. Someone has an idea where the error might be, because I would have said now that the rectifier has one away. LG
