All these regulators can be mounted under the seat or in the toolbox, they do not need to be 'in the wind' like the Zener diode

Other traders sell similar looking products, if it hasn't got an A Reg label on the back it isn't an A Reg

Over 4500 A Regs sold since 2010 (Aug. 2015)

A REG SIX £34.95

This 6V regulator will suit any Lucas / Miller type 6V alternator and will give proper Voltage control to prevent boiled batteries/blown bulbs and allow the safe use of AGM batteries such as the Cyclons. Because of the way the alternator is wired more power is available when the battery is low. Can be wired Pos. or neg. earth. Very reliable & simple to install

They come with full instructions. AREG6

67 x 59 x 24MM mounting holes 6MM dia. 55MM apart

A REG ONE £34.95

These 12V regulators suit any Lucas / Miller / Wipac type alternator and replace the Zener diode and the rectifier. They can also be used when converting from 6V to 12V and come with full instructions. Very reliable & simple to install.

They are rated at 25A which is 300W and have been tested to max. output with our 200W alternator

They can be used without a battery if a Capacitor is fitted, see below. Can be wired Pos. or neg. earth

They are suitable for std. 120W & high output 200W alternators. AREG1

67 x 59 x 24MM mounting holes 6MM dia. 55MM apart

They also suit the Alton alternator/electric start as supplied for Commandos. They are not suitable for the Alton Dynamo replacement alternators.

This replaces the Lucas 2MC Capacitor, the blue thing the size of a cotton reel under the seat on Commandos. It enables the bike to be started without a battery, providing it is fitted with the RM21 alternator or equivalent.

A failing capacitor can slowly discharge a battery, so if your battery is dying unexpectedly early it is worth changing the capacitor first.

The 2MC was 4700 microFarads, & so is ours. Larger capacity capacitors are available at an inflated price but there is no advantage.

Fitting a capacitor to any alternator bike will slightly increase its charging potential, may increase battery life & could prevent damage to a Regulator/Rectifer by minor unnoticed faults.

They are now smaller & robust enough to not need mounting in a wire spring, just cable tie them securely.

The Zener diode was used on Alternator equipped British bikes from the mid 1960s to give a cheap and effective 12V Voltage control.

The A Reg Regulator/rectifier above is a better system


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 electric start Triumphs and Nortons.

The older Lucas rectifiers needed fins to dissipate 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, and supplied with wiring instructions. Rated up to 25A £5.25

Dimensions are 30MM x 30MM x 23MM




This is a Genuine Lucas bridge rectifier as fitted to British bikes early 1960s onward and will also replace the earlier larger selenium rectifiers.

Positive earth, models 1962 on REC10135 £57.50




A 6V Lucas/Miller dynamo in good condition is capable of powering a 12V system allowing the use of modern lighting components. The E3H "short" dynamo will happily run a bike at 12 V fitted with the 35/35W Quartz Halogen headlight bulb. Whereas if everything is in good condition, the E3L as fitted to most 1950s twins is capable of powering the full 60/55W. There is no need to alter the dynamo in any way.

The V Reg can also be used on many foreign dynamo equipped bikes. See Bosch Dynamo Wiring


This device is proven and reliable. Available in Positive or Negative earth, also to run a 6V system.

The 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.

Fitted to the inside of a Miller regulator

The regulator must be used with a good battery (minimum 5 Amp-hours) and is guaranteed, subject to correct fitting and use with a good dynamo.

New features include: Current limit to the field winding, allows excellent performance when using a 6V dynamo on a 12V system while not straining the dynamo. 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. 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 by cutting a simple wire link will run a 12V system.

46.95 Pt.nos. VREGPOS & VREGNEG

A 150W version is available to suit small cars such as the Austin 7 £62.95


Dimensions are 50 x 42 x 22MM

A battery will be needed with a capacity of 5 Amp/hours minimum. The Westco 12V7L-B which measures 114MM x 71MM x 113MM is a good choice. This is a sealed AGM maintenance free battery and will fit the battery tray of A7/10s, Pre-unit Triumphs, Dommies etc. with room to spare.

(Low Voltage Lamp Driver)

This simple device connects between the ignition switch & earth. 12V only.

When the ignition is turned on the lamp lights.

When the engine starts and the battery is being charged the lamp goes out. No charge it stays on.

This can be used on an alternator system or a dynamo system used to power coil ignition.

Replaces the warning light assimilator on Commandos. Full instructions are supplied.

The Battery Status Monitor (BSM) is a LED voltmeter designed to monitor the Voltage across a 6 or 12V battery. It is an easy to see what is happening to the battery, charging - not charging - over charging. Battery low - fully charged.


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

At 12V Battery is still low and the LED maintains 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

Over 15.25V Overcharging. Fast red flash.

The dia. is 10MM with an 11MM base. this clicks into a 14MM holder

Also serves as an ignition on reminder

On coil ign. bikes it is wired to switch off with the ign. so connect it to the live feed from the ign. switch or the coil.

On dynamo bikes it can be wired to the speedo light.

The BSM is protected against reverse connection and unlike an Ammeter is immune to vibration. An ambient light sensor is incorporated that dims the LED for night time.



This is a compact digital Voltmeter that will continually display the battery Voltage.


Two sizes available, please state which size.

1/ 27MM x 15MM x 17MM 2 mountings for 3MM (6BA) screws

2/ 42MM x 13MM x 24MM 2 mountings for 4MM (4BA) screws

Suitable for 6V & 12V systems, it will display from 3.5V - 30V

It should be connected to the ign. circuit on coil ign. bikes and the pilot/speedo light on dynamo bikes. CE marked
