1986-Present Sportster Main Wiring Diagrams
The drawings below have been created using the factory schematic drawings from the FSMs as reference. They are available here
but are not intended to replace the factory drawings. Some parts symbols are generic, may not represent the actual period parts
and have been spread out for clarity from the originals style drawings. However, the parts are labeled.

Despite this representing an actual HD wiring diagram, the Voltage Regulator is shown connected to the wrong side of the Main Circuit Breaker. For the sake of safety, please connect the Voltage Regulator to the opposite side of the Main Circuit Breaker from that shown on this & the HD wiring diagram.
