I went though my second regulator rectifier in a month. At first i thought it was the stator so i swapped it out for a different one. Still did not charge. So I then swapped the regulator, And I worked fine for 3 weeks.
Then I started to notice a sulfur smell for a few days of riding and then the bike stoped charging again. I never have had any problems with the charging system until I repalced my stock head lite bulb for a blue bulb don't now if that has any thing to do with it. By the way its a 1991 f2

I tested my batterie and it was bad which was weird cuz id just got i a month ago and the new 1 seems to charging at the proper voltage so i guess ill see what happens. And yes an new bike is long over due iv have this tank for 8 years. but inbetween job so not this summer.

 

Buke dead again it smelt like sulfur, then i had no powed at all ???????????????????
