Hello,i have been noticing lately that my car's battery light comes on during moderate acceleration and goes off once i let off.The other day i turned on the a/c and the blower shut down and i began to loose all of the powered accessories,dash lights,radio,climate contol etc.I pulled out the alternator and had it tested,no issues,the battery is only about 5 months old,i also replaced the neg battery cable thinking a grounding issue might be the problem all to no avail...Once i get a jump and keep the car hooked to the other vehicle everything works fine,but once i disconnect the cables the lights start to dim and everything goes haywire....Any ideas,please help!!!!!
