I was going through voltage regulators every couple of years, too, so a couple months back I decided to give one of Bill's a try and I simply love it! I had irregular charging (at least according to my gauge) where it would charge for a few minutes after starting and then quickly fall back to neutral or even negative when I used the turn signal or the brakes, and the headlights would be dim, too. Not cool. I read some comments here where guys with similar problems had tried the electronic (mine were all old-school mechanical) and their problems were solved. I figured for $20 bucks it was easily worth a try, and so far so good. I have had mine 4 or 5 months now and I could not be happier with it. I still monitor my gauge frequently when driving and it now behaves just like it should, it never shows a discharge, and my headlights are always nice and bright with no apparent strain on my electrical system. Magic!
