Downside (or Upside) of 1-wire versus 3-wire Alternator???

Post #1 by james singleton » Fri Jan 29, 2010 3:42 pm

I am curious as to any thoughts/comments concerning the use of a "1-wire" alternator versus the use of a "3-wire" alternator. Is there much difference such as longevity of the regulator, etc.??? Thanks, James

Thanks Wallaka, that was a great article on both the "one wire alternators" and the "three wire alternators" systems. That article was just what I was looking for; it answered most of the questions I had concerning the two systems. Thanks, James
