Terminal Identification:
F= Field (F terminal on alternator)
2=Stator (R terminal on alternator)
3= B+
4= Light

The regulator is grounded to the rad support. I suggest that you check the ground connections from the regulator to the rad support, rad support to frame, and frame to engine.

Use of those uninsulated braided straps is a good idea at any point that has a moveable joint (like a hood or trunk lid) ... or any part that may be rubber mounted (i.e. rad support, truck pickup box).

NAPA (Echlin) Part Numbers if you happen to need them:
VR142 Voltage Regulator
VRC142 Voltage Regulator Connector
VRA142 Alternator Connector
