every morning i start my car everyhting is fine. i have a voltage gauge on my deck. it says its fully charge. when i do some spirited driving it sometimes flickers up and down. and last night when i was driving fast on the freeway the battery started dying so low that everything from my deck to my speedometer lost power.

most of the time i drive normally, the voltage wouldnt change dramatically


i replaced the battery everysince i got the car. do you think its my altanator? im guessing wiring?

PLEASE HELP

 

take your alternator off and take it to your local auto parts store and they will check it for u....Y would u guess wiring?

 

i had the car the same problem before and after the swap. i think we used another altanator.

before the voltage use to be low and when i drive fast it woudl charge it. now its the other way around.
