[Nor Cal Al]

I had a vintage alternator built for me and had a pack put on the back to make it a 1-wire (ie., add-on regulator). I have underdrive pullys and they said the charge may not turn on until it gets rev'd once. My experience has been that the charge will turn on, run at about 14 volts and come down or shut of when the battery is charged providing there is not a great load on. Mine runs for quite a while because the Beast does not get out once a weekend or maybe everyother weekend. Less over the winter.

My first pack failed and I had 18 volts to the battery.
