You should have 3 wires on the generator. The ground is a smaller probably black wire and goes to a screw on the case rather than the terminals with fastening nuts. From the generator it goes to the L fender or radiator support where the 3 terminal headlight junction block is fastened. Ground goes to one of the mounting screws holding terminal strip in place and may have several others on the same screw--although some could be attached to the other mounting screw. One of those, again probably black will go back to the regulator and either fasten to a small screw labeled ground or to one of the regulator mounting screws. Ideally that wire to regulator will be continuous or at least on the same screw as the one from generator.

The regulator needs to be at the same reference to the generator and not be getting it's ground through a lot of engine mounts, bolts, sheetmetal and cast iron.
