On 6-volt generators with a diameter of 90 mm, the voltage regulator is mounted directly on the generators. at the time, Volkswagen chose this solution to minimize the number of connections (thus minimizing the risk of malfunction).
On the latest 6-volt generators with a diameter of 105 mm, the location has changed. Depending on the VW model, the location varies from elsewhere in the engine compartment to under the rear seat.
When the engine is running at high rpm, the voltage regulator adjusts the generator's voltage to a steady level. If the voltage regulator fails, the charge current indicator lights up (when the ignition is switched on, this indicator should light up; if it doesn't, the voltage regulator has failed; once the engine is running, this indicator should go out).
This 6-volt voltage regulator looks original on the outside, but it's 100% electronic on the inside. This makes the regulator not only more resistant to moisture, but also much safer, more reliable and much more accurate to set. A classic voltage regulator with contemporary technology, a good example of reproduction that surpasses the original.
Note: Once assembled (if only for testing), a voltage regulator cannot be returned.
