I've heard where putting a relatively large capacitor (at least 2200 uF) across the alternator output smoothes out the rectified AC and makes the DC components happier. I have a rather large super cap across the battery on my '95 Grand Cherokee and the battery keeps going. It's dated 4/16, which means it should have died around 2 years ago. Your new regulator may have some sort of capacitive filtering that makes it run better.
