The O.D. of the stator is 5.0" (127MM) and the depth 1.4" (35.5MM) The mounting holes are on 4 3/8" centres.

The Zener diode was used on Alternator equipped British bikes from the mid 1960s to give a cheap and effective 12V Voltage control. If converting from 6V the Zenor can be the easiest way to do it.

The existing rectifier can be used, but the Zener has to be mounted on a heat sink. Commandos used the ally. footrest plate, so any lump of earthed ally. will do

Zener diode + as standard, but now also available in - earth £20.00 Triumph type Heatsink £15.00

These 12V regulators suit any Lucas / Miller type alternator up to 150W and replace the Zener diode and the rectifier and have to be used with a battery or capacitor. They can also be used when converting from 6V to 12V and come with full instructions.

V- REG 2A DYNAMO VOLTAGE REGULATOR, 6V - 12V UPGRADE

A 6V Lucas dynamo in good condition is capable of powering a 12V system allowing the use of modern lighting components. The E3 "short" dynamo will happily run a bike at 12 V fitted with the 35/35W Quartz Halogen bulb. Whereas if everything is in perfect condition the E3L as fitted to most 1950s twins is capable of powering the full 60/55W Xenon bulb. This is what I use on my A10.

What is needed is a Solid State Voltage Regulator. This converts the system to run on 12V. Supplied by A.O.Services, this device is proven and reliable. Available in Positive or Negative earth, also to run a 6V system.

This is a solid state encapsulated regulator for motorcycles using the Lucas E3 type dynamo. The TEB Technology dynamo regulator is designed to replace the mechanical regulator with modern reliable semiconductors, and can handle up to 100W at 6V and even more for the 12V version, provided the dynamo is capable of delivering this power. The regulator must be used with a known good automotive battery (minimum 5 Amp-hours) and is guaranteed, subject to correct fitting and use with a known good dynamo.

The V-Reg 2A is an upgraded version of the original V-Reg now fitted in a metal case. New features include: Current limit to the field winding, allows excellent performance when using a 6V dynamo on a 12V system. Tougher electronics, with the introduction of higher energy spark suppression to reduce spikes generated by the dynamo. Improved "thermal foldback" which progressively reduces output power if the regulator gets too hot, indirectly limiting the dynamo from excessive current. Higher specification voltage reference. Better servo loop stability, with new electronics which 'predict' when the output voltage is nearly correct and control the field current earlier.

The V-Reg 2a will run a 6V system or buy cutting a simple wire link will run a 12V system.

£41.95

A 150W version is now available to suit small cars such as the Austin 7 £46.95

Dimensions are 48 x 40 x 22MM

A battery will be needed with a capacity of 5Amp/hours minimum. We recommend the YTX7L-BS which measures 114MM x 71MM x 113MM. This is a sealed maintenance free battery and will fit the battery tray of A7/10s, Pre-unit Triumphs etc. with room to spare. The capacity is 6AH and the cost £27.90 + £6.95 P&P.

The bridge rectifier shown here replaces the lucas finned rectifiers fitted to British bikes from the 1950s to the late 1970 and will suit all models 6/12V fitted with an alternator except the later electric start Triumphs and Nortons.

The older Lucas rectifiers needed fins to disipate the heat generated, these are more efficient in rectifing all the current so need no finning and supply more current to the battery. Easy to connect, can be supplied with wiring instructions. Rated up to 25A they cost £4.95

Dimensions are 30MM x 30MM x 23MM

Under 10.75 Volts. If the battery Voltage is very low, the LED will flash red slowly

.At 12V the battery is still low and the LED will maintain a constant red.

12.5 - 13.5V battery fully charged (engine not running) the LED will show orange.

Over 13.8V battery charging the LED shows green
