Equipment & coverage

Match the arrangement.

Magneto ignition only. This edition does not include an electric starter or a battery-lighting circuit.

These are functional schematic drafts. Independent circuit and fitment review is pending. Confirm the connections and equipment on your vehicle before using a drawing for wiring work.

Reading the sheets

Color follows function.

Muted colors distinguish battery/starting, generation, ignition, lighting, horn, and frame-return circuits where shown. The colors are an editorial reading aid and do not identify every original insulation color.

Dots join conductors. Controls and loads are drawn as grouped assemblies; the layout is not a physical harness routing or terminal-position guide.

Included in this year/model edition
