Our heavy duty Voltage Regulators for the 6V Pos. Grd. systems is just the ticket for a Generator upgrade! Takes the place of the 3 position Headlight/Charging switch and adds a nice upgrade to the 6V system. Curved chassis mounts on top to the Generator in place of the Reverse Current Relay or Cutout.  Comes in a flush mount also for mounting in on the Tractor or in the toolbox of the B,IB,C&CA model Tractors.   USA made!  Not Chinese junk!
