If it is the squarish 6V solenoid then yes if the generator and wiring is intact. Otherwise, you can just ground the other terminal. Both Autolite and Delco had similar designs although the connections were in different locations. The ones toward the firewall sound like Delco. Will throw in an Autolite diagram just in case.
That ground connection to the regulator was a safety feature which allowed the solenoid to get ground thru the generator windings when engine was not running. Once the engine was running and generator was putting out voltage, then both terminals were at the same potential so starter could not accidentally engage if the carb switch was out of adjustment or acted up.
Was somewhat problematic at times so Packard issued bulletins removing the ground from regulator/generator and going direct if the owner had reported problems. Finally dropped the feature completely.
