Wiring diagrams for Aermacchi Harley-Davidson motorcycles, redrawn circuit by circuit: battery, charging, ignition, lights, stop light, horn and, on the 12 volt models, starter and turn signals. Every wire is labelled with its colour. Open a group and choose your model.

Our own drawings, based on the factory workshop manuals. Where wires disappear into the loom or the original is hard to read, the connection was worked out from colour and function; each page lists those points under “Watch out for”. Not an official Harley-Davidson or Aermacchi publication.
