Our heavy duty USA made 12V Voltage Reguators are the ticket when restoring your 12V Generator or Alternator system when using a "DN" series Alternator.  Flush mount design mounts anywhere on the Tractor or right in the OEM spot.  These get mated to the Generator that you have, so before ordering, make sure you send us your Generator number this way we hook you up with the correct VR that would work with that particular Generator. VR is used for 12V Neg. Grd or 12V Pos. Grd.
