In the service manual 7-1 they give you a trouble shooting chart, kind of sounds like some of the symptoms you have.
Yes, this is the first edition written in 03, I believe you are covered.That's what I'll do then. I downloaded a manual from a link on this site YXR660FAS. My rhino is a 2004 660. Hopefully this is the right manual for what I need. Thank you for your help! Probably have to fix everything in there, but at least it's less work than the alternative. Thanks again!!
