Yeah i get that. Iv not seen 14v+ ever in this car. Rests at 12v. Idles at 12.4v And 13.5 when my foots in it... like 2500rpm.. and dips to 11.3v when music is up..i got 2 new group 78 800cca battery and a new 90amp alt.big 3. Never saw 14vMakes your voltage more constant so instead of seeing 14.8 one sec and 11.8 the next it will discharge some to keep it up so you don't get ups and downs in your voltage.
