How far of a voltage drop. My truck does drop below the 14 mark when i come to a stop and have load on the electrical system (headlights on, defroster, heat blower, fog lights, blinkers, etc) the alternator puts out more power the faster it is spun (engine speed). When stoped the amount being put out is less than that being put out than when you are driving at a normal speed
