i was having a really low voltage reading so i bought a new alternator from ford. its been about a week and all was good never dropping below 13.7v and had a high of 14.2v. well today has been the warmest day since i have had the new alt. when driving home from work i noticed it started dropping down around 13.0-13.2v when stopped at lights or sitting in traffic. slowly climbs back up when i get going. only thing i had running was my meziere pump, radar detector, and aeroforce gauge. is this normal? i havent had my aeroforce long so i dont know if it is normal for the volts to do this or not??
