On 396 alternator has plug-in connection (2 Wires) and hot wire screw-on with rubber cap. Alternator also has connection for ground, what is this grounded to? I don't ever recall hooking up a ground to this connection previously, is it necessary? What is correct? Thanks....

The mounting bolts should be a good enough ground. The only time I've heard anyone having a big problem was with a powdered coated alternator. The bolts wouldn't "bite" through the coating.
