<VV> Alternator Regulator Voltage Setting

[Padgett]

While going through everything else I noticed very high battery voltages. 
Pulling the regulator off (nut inside the rubber bushing which spins takes 
a 5/16" wrench) & hooking to a power supply I found the regulator was 
regulating but at over 16v. Backed things down to 14.3-14.5 volts but book 
only discusses setting on the car and when hot.

Is this a reasonable cold setting ?
