Norton 88 SS and 500cc Twin Electrical Wiring Diagram – 12 Volt Magneto Ignition, 1964
Download the complete PDF version using the green download button at the top right of this page for the electrical wiring diagram covering Norton 88 SS and 500cc Twin models with 12-volt magneto ignition. This single-page factory-style schematic shows the charging, lighting and ignition cut-off circuits, together with switch rotor positions and wire colour references.
The diagram includes the 2.6-volt battery arrangement, alternator, rectifier, Zener diode, ammeter, lighting switch, dipper switch, magneto, magneto cut-off switch, horn, horn push, stop light switch, headlamp main and dip beams, pilot light, tail light and speedometer illumination.
A note on the schematic explains that on earlier machines the Zener diode is connected as drawn, while on later machines it is connected to the NW terminal of the ammeter using a brown/white diode cable. This makes the drawing especially useful when checking period wiring variations during restoration or fault tracing.
