This is a stock replacement voltage regulator with screw terminals which comes already adjusted. For use on negative or positive ground systems.
When fit with a stock generator, we tend to swap the car to negative ground (if that switch hasn't already been done) and install our solid state regulator for a reliability upgrade that requires no adjustment throughout the life of the unit (unlike this one). If you're thinking of upgrading your electric system with an alternator conversion kit, then we recommend to install a dummy regulator in place of this regulator.
