Riley 9 & 12/4

12V Dynator to fit the Riley 9 and 12/4. Produces 50A compared to 20A from the original dynamo. Negative earth.

The shaft through the unit is not continuous, so the crankshaft of the car cannot be turned by rotating the dummy shaft protruding from the front of the Dynator.

Electrical connection to the vehicle is easy and straight forward. Fitting instructions are given in the downloads section below.
