Thanks.

I have experienced a couple of events where my engine =
monitor alerted that there was an over voltage situation.  
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 determined =
to be the problem. 
 
I have an adjustable regulator and =
adjustment was unable to fix the issue. 
 
I replaced the unit =
with a properly 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:  What numbers should I be seeing?  Is my 15V limit =
correct?  Would spikes of 16V damage my system? 
Would constant =
readings of 16V be bad? Any suggestions for actions needed to assure =
reliability?
 
Thanks for your input.
