Voltage Regulators

6 or 12 volt regulator in one unit. simply cut the blue wire for 12 volt use or leave intact for 6 volt use.
Simplify your wiring: replaces rectifier and zener diode on British bikes (single/twins and triples).

Single-phase rectifier/regulator for use with any two/three wire permanent magnet alternator, up to 200 watts, including Lucas RM21 AND RM23.

Can be used to convert 6 volt 3-wire alternators
to 12 volt charging (see link to data sheet).

Rectifier/regulator for use with any three phase, three wire permanent magnet alternator, up to 200 watts, including Lucas RM24.

Simplify your wiring: replaces rectifier and zener diode(s) on British bikes (single/twins and triples).

Regulated output: 14.2 volts

Dimensions: 80mm x 80mm x 30mm deep

One year warranty.

General purpose 6/12 VOLT dynamo regulator, suitable for most classic/vintage motorcycle dynamos.
Replaces original Lucas/Miller mechanical cvc regulator. NEGATIVE GROUND ELECTRICS ONLY.

To maintain originality, the dynamo regulator unit is small enough to fit inside a Lucas or Miller case, or it can be mounted on its own.
Fixing is via a single M5 stud. The unit produces a very low level of heat, but if heavy continuous loading is expected we recommend mounting in a good flow of cooling air. The maximum safe continuous output current of the unit is 12 Amps, but note that if this current draw is prolonged the dynamo will be damaged.
Before fitting the regulator it would be useful to confirm that your dynamo is giving a good charge and of the correct polarity (see detailed description).
Seek qualified assistance if unsure.
