not familiar with your tester, but if its showing around 14 to 14.5 volts at 3000 rpm, and the battery is good you are good to go. voltage fluctuates normally from idle upwards but shouldn't exceed the 14.5 volts

hope that helps a bit

In colder ambient temps, the voltage should reach in the middle 14s, maybe even 15

when it is warm, on a 70* day or warmer, the regulator should pull it back to around 13.6

just as a comment, I have a Digital cigarette lighter voltage monitor.
I like it, always right where you can see it while driving.

on a 30* day, I started up my 2001 Chevy Suburban and went to town.
that thing went above 15.0 for a while.

about a mile later, it was around 14.77 and stayed there for over ten miles.

Coming home, after many stops at some stores in town, and idling thru the parking lots,
it came down to about 13.9 to 14.0
