My upper limit is set at 15 volts and t= he display was showing 15.2 to 16 volts.=20 After troubleshooting the system the regulator was determined to be the prob= lem.=20 I have an adjustable regulator and adjustment was unable to fix the issue.=20= I replaced the unit with a properly adjusted one and have about 8 hours on i= t without problem. The system displays 14.2-14.7 at all times in cruise.=20 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 b= ad? Any suggestions for actions needed to assure reliability? Thanks for your input.=20 Jim Scales IO550G Super ES=
