Answer
Hi Brian,

I'll try and help you, but we need to communicate on the same level. Visit this link: "www.yamaha-motor.com/"

Once the page opens, click "Parts & Service" from the top menu bar, then click: "Parts Catalog" from the drop down menu. A new page opens, select the year of your ATV "1999" from the left menu, select "Generator" from the next menu. Look at the parts microfiche and indicate by number which parts you are referring to in your question description.

I need your email address as requested. I retrun repair information files via email.
