Alton Electric Starter Kit Installation for Norton Commando 750 and 850
Download the complete PDF version using the green download button at the top right of this page for the Alton electric starter kit fitting instructions for Norton Commando 750 and 850 models. This guide covers installation of the Alton eKit on pre-MK3 Commandos with either positive or negative earth electrical systems, while noting that it is not intended for early distributor-equipped 750 Fastbacks or factory electric-start MK3 models.
The instructions begin with kit contents, required tools, workshop preparation and important checks to carry out before installation. These include inspecting the isolastic mountings, Woodruff keys, crankshaft threads, crankcase threads and drive-side crank seal, as well as confirming that a suitable battery is fitted before proceeding.
The main installation section covers fitting the inner casing, central stud, primary drive components, sprag clutch rotor assembly, steady plate, stator, outer primary cover, alternator wiring, starter motor cable, battery, relay and starter button connections. Later pages include positive-earth wiring guidance, an alternative negative-earth wiring diagram and important final checks before first use.
The guide also includes a dedicated appendix covering belt-drive primary installations, with diagrams showing spacer and alignment considerations for standard triplex chain, RGM-style and Norvil-style configurations.
