CLASSIC MINI DYNAMO VOLTAGE REGULATOR CONTROL BOX GEU6603 NCB101 CAR 5P9
Classic Mini Dynamo Voltage Regulator Control Box
Many charging system problems can be traced to a malfunctioning voltage regulator. And while the workshop manual gives a detailed procedure for checking and/or adjusting one, the only thing that has ever worked is to just replace it!
If you still have a dynamo (generator) you’ve got to have a regulator that works. This is the later version with blade terminals, the earlier one with screw terminals is no longer available.
