Genuine Lucas RM20 Rotor, 6 Pole with welded 0.75" centre. As fitted to most British motorcycles late 50's to 70's equipped with alternators. 74MM O.D. Suits older pattern & genuine Lucas single & 3 phase stators. Fits stators RM18 & above.

Lucas Pt.no. 54202299

Pt.no. ALT10105L £129.95

Rotor shown as supplied with 'keeper plates' for storage

Genuine Lucas Stators

Single phase 12V 120W 2 wire (RM21) LU47205 Pt.no. ALT10109 £124.95 Used with the A Reg Six, 6V regulator/rectifier, this stator is also suitable for a 6V system, replacing the old 3 wire stator.

This is the only Lucas stator that will run a 12V system without battery. A capacitor must be used (Pt.no. CAP01 £11.95)

Single phase 12V 200W 2 wire (RM23) Pt.no. ALT10190 £124.95 These are rated at 200W but max. output is almost 300W at 10,000 RPM. Use the RM21 if your bike is all LEDs

Three phase 12V 175W 3 wire (RM24) Pt.no. ALT10192L £124.95 (Use with the A Reg Three, see below)

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. A Reg./Rect. is essential if fitting electronic ign. to a 6V alternator bike.

They come with full instructions. Pt.no. AREG6

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

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. Pt.no. AREG1

On a Commando the warning light assimilator should be disconnected or replaced by our Charge Warning light driver (NCLD)

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.

Pt.no REG10121 at £84.95

A high output 200W Podtronics regulator.

As supplied with Alton generators.

65 x 75 x 30MM 6MM dia. mounting holes 65MM apart

Three phase 200W version Pt.no. REG10124 £89.95

The Red wire is positive, the Black wire negative. Connect the other way & it will go pop.

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.

£11.95 Pt.no. CAP01

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 Pt.no.REC001

Dimensions are 30MM x 30MM x 23MM

This is a new Lucas rectifier as originally fitted to Lucas equipped single phase 6/12V alternator bikes of the 1960s & early 70s.

It is a simple bridge rectifier & does not provide any Voltage control, ideal if you really want everything original looking, otherwise the A Reg One & A Reg Six above are a better, cheaper bet.

Pt.no. REC10135

£49.95

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.

£49.95 Pt.nos. VREGPOS & VREGNEG

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 2B will run a 6V system or by cutting a simple wire link will run a 12V system.

A 150W version is available to suit small cars such as the Austin 7 £69.95

Pt.nos.VREGCPOS & VREGCNEG

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.

How to Repolarize a dynamo An easy way to test a dynamo

This is a double sided switch that is wired so that when in the 'Off' position it shorts the mag cutout to earth & the other pole breaks the battery connection preventing any discharge through the regulator.

It also provides some extra anti-theft properties and prevents a battery going flat if the bike is unused for long periods.

It also prevents accidently leaving the lights on & flattening the battery.

If left in the 'On' position after the engine is stopped, it causes no problems, the effect is just as if the switch had not been fitted.

An existing cut-out button can be left in place. A 20MM hole is needed for mounting.

Supplied with wiring, two keys & instructions

Pt.no. SWMAG £29.95

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.
