You could program the Arduino to re-engage the alternator if the voltage drops below some set threshold.
The trick would be keeping the battery from frying, which might be where a supercap and DC/DC converter might come in to act as a buffer.

This is also a great idea to be explored. The supercap bank would have to be sized appropriately, even over sized to protect the battery. Could a bleed off resistor be used as well in this case?
