I have experienced the alternator over charging the system. When revving up the
engine, it goes up to 17 volts. Drop back to idle and the voltage drops back
to 13.5V. It has done it rarely for a moment or two when first starting the
engine. Then it did not recur in flight. Yesterday it went up to 17V. while
in cruise. I reduced the RPM to about 4500 and the voltage went back to normal.
I returned to the field with no detectable harm to anything. All the
electronics
will take 12-24V so they were not harmed. The overvoltage did not last
long enough to harm the battery.
Anyone else had this problem? Do I need a new voltage regulator? I plan to
check
connections on the battery and such to see if something is loose.
