When this happens all my lights dim but I dont have any loss of power. When i accelerate the gauge returns to about 14. When Im stopped at a light the gauge drops again and bounces. Its worse when I have the rear defroster on or the vents on 4. It only seems to drop at low RPM.I replaced the battery about 2 months ago and the alternator about 6-9 months ago.I checked the grounds batt to engine, engine to chassis, chassis to batt and all of them were fine. Does anyone know what could be causing this to happen?</blockquote>
