This is the  Reg 2C Voltage regulator for POSITIVE EARTH dynamo equipped bikes. (See our other listing for negative earth)

Full instructions are supplied

This device is proven, reliable & easy to install just using the existing wires connected to F A D & E on your old Voltage regulator. Many thousands have been supplied over 20 years.

As supplied it will suit a 6V system, but by cutting a wire link on top of the unit it will run a 12V system without any alterations to your dynamo.

There are cheaper Voltage regulators available but I sell this one for its performance & reliability.   If you read the instructions & connect it correctly, IT WILL WORK.  What it won't do is fix a dud dynamo, so if it doesn't charge check the dynamo before sending it back.

Made in England
