Please Note: The DVR2 (Negative or Positive Earth) is the only regulator we sell today. The DVR2 is suited to Lucas and other dynamos with 'field to earth', and is good for up to 10 Amps (not suitable for Bosch style machines).
We discontinued our "Jeep" Autolite replacement, and DVR2-D Dynastarter units in October 2018.
We transferred sales & support of the DVR4 & DVR3 current limited regulators to ElectroDynamic Solutions in mid-2019 (click on the link above).
