I have the National Luna with the sensor. Mine doesn't always go off and can't explain other than it appears to be when I let the truck sit for a while. On startup the alternator will surge for a few minutes to quickly charge up the battery. If it goes off after a few minutes I wouldn't worry about it. Mine doesn't go off for 5 minutes by any stretch. Maybe 30 seconds or so when I first crank up. As Dave mentioned almost 15v is a little excessive. Is that what your reading or just a guesstimate?
