Default Was it the alternator or the voltage regulator?

I made the mistake of disconnecting the battery in the boat while the
engine was running.
Now, as expected, my alternator is not producing juice to charge the
battery.
The alt. is on an older Ford 302 , is a 3 wire, and has an external
regulator.
What is it that goes when I made this mistake - the alternator or the
regulator?
Which should be replaced?

Thanks - Michael

It's most likely a diode in the alternator.

If your alternator is as old as the "older Ford 302" this might be a
good excuse to take it to a shop for an overhaul or a rebuild. While
replacing the (probably) failed diode, the shop can inspect the rest of
the mechanism and replace or adjust components as required.
