Alton generators

How to order

When ordering Altons please give your daytime phone number
Alton Generators have been designed to provide enough power to give modern levels of lighting and reliable levels of charging for bikes even equipped with electric starts. They are 12V AC alternators and are used with a solid state regulator/rectifier.

The Altons are 12 Volt single phased AC generators specially designed to replace the 3" dynamos on British motorcycles. Their brushless design is based on permanent magnet technology, modern simple and reliable.

They provide 150 watts at their maximum and at about 90 Watts at ordinary cruising speeds allowing the use of modern lights while charging the battery. An Lucas E3L (A10s, Triumph twins etc) only give 60W maximum (more on 12V though). Miller as fitted to Vincents 50W if you're lucky.

They have the same dimensions as Lucas and Miller and they maintain classic standard appearance

Early versions of the Alton were 3 phase and some proved to be unsatisfactory, the current versions have been made for over 5 years & are very reliable.

The units are supplied with full fitting instructions, and simple wiring diagram.

There is a 2 year warranty on all Altons

Prices include a Podtronics Regulator/rectifier
