Interesting. Cause I go to junkyards in CA and probably 75% of the 67-70 cars that I look at have the original regulator still on it.
The voltage is temperature compensated by the regulator. The remote regulator more closely tracks the temperature of the battery than the integral regulators. Which is a big deal for battery state-of-charge and battery life. And no current OEM (and we did a lot of competitive analysis) uses an alternator system without some test and failure indicators, but that's what you get with a one-wire system.
The one-wire system will work fine, but don't convince yourself that it's *far* superior than the original, cause it's not.
kurt,you speak the same language as me.most amature do it yourselfers prefer to eliminate the regulater,and most professional mechanics prefer the cars the way they were deseigned.
