Harley-Davidson does not provide wiring schematics for its motorcycles on its official website. However, customers can contact Harley-Davidson customer service with service and maintenance-related inquires regarding their motorcycles. Harley-Davidson also operates a nationwide network of franchised dealerships that are authorized to provide service and support for Harley-Davidson motorcycles. Customers can use the dealer locator tool on Harley-Davidson's official website to locate and contact a dealership in their area.
Auto parts stores such as NAPA or Autozone carry a range of repair guides for personal vehicles, often containing wiring diagrams. Customers can either visit their official websites, or contact a nearby auto parts store to see if they carry the appropriate guides for their Harley-Davidson.
The company Haynes also provides repair guides that contain wiring diagrams for many vehicles, including a variety of Harley-Davidson motorcycles. Auto parts stores often carry Haynes' guides in stock. Alternatively, Harley-Davidson owners can visit Haynes' official website, browse and purchase appropriate repair guides for their motorcycles.
Harley-Davidson recommends that customers bring their bikes to Harley-Davidson authorized dealerships for service. The company notes that its authorized dealership technicians have manufacturer-approved training, access to advanced diagnostic and repair technologies, and factory-provided repair parts and techniques for Harley-Davidson motorcycles.
