Once the alternator starts charging voltage from an outside source is no longer needed on the excite (No. 1) terminal for the alternator to continue to charge, in fact, it is providing internal voltage on that terminal. That is what turn the charge indicator light off on systems equipped with a light. Once the alternator stops charging it will again need excite voltage for it to start again.

Delco regulators should be equipped with a safeguard feature that shuts the alternator down if there is no voltage sensed on the number 2 terminal. With all the after market regulators available you can find some that shut the alternator down completely and some that will go to maximum charge. Others will maintain a preset voltage.
