Sure it makes sense, what he did was to bypass the regulator cutout. See my post above where I suggested you subject the cutout to a simple test.

There are 3 units within your regulator, one controls voltage, one amperage, and one connects (when the engine is running) and disconnects (when you turn off the engine) the generator from the battery; this one is the cutout. I suspect it is not functioning. Do you need help to identify which unit within the regulator is the cutout? It's the one with the largest, heaviest windings on the core, and adjacent to the BAT terminal. Why do you need the cutout? Because without it the battery would dicharge back thru the generator if they stayed connected when the car wasn't running. And in short order it would probably "cook" the generator.

Are you sure both the old and "new" regulator are the correct ones for your system? What year and model is this Packard? Delco or AutoLite system?

No reason to get confused by + ground. System ground is the polarity of the battery terminal connected to the engine block.
