Hi, Mcninjamick the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have.

Hi Ahlester01, for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix or parts inquiry. If necessary transport your vehicle to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue. Good luck and have a nice day.
Under your tank and likely will need to remove one or both side panels.... I strongly recommend you purchase a Service Manual for your ride. Either Yamaha or Clymer's will help you greatly. Good Luck! Bob
