system volts too high?

[james accordino]

I had to replace the Autozone "lifetime" alternator
again (3rd time) because of a faulty high cutoff
voltage reg.  These are plain smooth black with NO
markings.  From Asia somewhere.  It would rountinely
peg my alt. gauge with readings as high a 20 volts on
the meter.  Turning ALL the accessories on high would
solve this short term.
