MADE IN THE USA 6 Volt Saddle Mount Regulator that will work on the SC DC LA & other 6 Volt Systems. This Regulator is meant for Postive Ground, but will work on Negative Ground. It will last longer if you switch your Negative Ground System to Positive Ground. Not a complicated thing to do at all, the only wiring change will be to reverse the wires on the back of the Amp Gauge. We try to offer MADE IN THE USA parts when we can, and here is your opportunity. We also stock an imported regulator for $33.00, but I bet this lasts longer.
