Today retuning from my flight my voltmeter started to complain "check
voltage".  The bus voltage was reading between 14.2 - 14.6 volts.  Right
after shut down the battery voltage was reading 13.3 volts.

Is this a sign of impending over voltage failure of the regulator?
I am using the stock 70 amp alternator.  Do I need to replace it right
away?  Use an external regulator?  Is it safe to watch it for another flight
or two and see what it does?  Is it possible that oil mist could have gummed
things up a little and spraying some contact cleaner into the alternator
might do the trick?

How much voltage is too much before I need to land right away?
Thanks all.
