This is perfect thank you so much 

I’m looking for an answer as well. 

Please help. Iv got an 1990 lt80 that will not charge the battery. I can’t seem to find the answer to the problem. Is it the rectifier or the Cdi box or something different all together. I can’t seem to find any rectifiers for it so I’m stumped and I don’t have a manual to read up and find the answer.
