Whats up I been monitoring my voltage and at times its at 14.6 which is great but other times maybe at low 13s or high 12s even with ac and headlights once it hits 12.7 it like to charge I obviously cant have this because my voltage to fuel pump drops about .5 vdc from the battery to fp my question is is my alternator going bad or regulator in it and also is there a votage booster for the 2005+ years ?
