I have experienced a couple of events w=
here my engine monitor alerted that there was an over voltage situation.  <=
br>My upper limit is set at 15 volts and the display was showing 15.2 to 16=
 volts. 
 
After troubleshooting the system the regulator was determi=
ned to be the problem. 
 
I have an adjustable regulator and adjustme=
nt was unable to fix the issue. 
 
I replaced the unit with a properl=
y adjusted one and have about 8 hours on it without problem. 
The system=
 displays 14.2-14.7 at all times in cruise. 
 
My questions are:  Wha=
t numbers should I be seeing?  Is my 15V limit correct?  Would spikes of 16=
V damage my system? 
Would constant readings of 16V be bad? Any suggesti=
ons for actions needed to assure reliability?
 
Thanks for your input=
