My 60 Amp alternator quite after 800+ hours in 14 years. I had it overhauled in
a reputable shop with new brushes, bearings, part of the case and an internal
regulator. It is a Denso clone Plane Power alternator. On the test bench in the
alternator shop it runs a steady 14.5 volts with varying loads. In the airplane
with Z12 architecture on the Skyview it runs 14.9 to 15 volts. what could
be the reason for the high voltage indication in the aircraft?
