I had my minivan stop running while i was on the freeway. My electrical seemed a bit off, the speed decreased and it slowly died. I tested the battery and it was fine, tested the alternator and it failed. I changed the alternator and still wouldnt start. I changed the battery as well and it worked for about 2 days and then it did the same thing. Radio started to flicker, all the lights turned on and the car decreased until it didnt run anymore?
What could this be? Bad gearing? A faulty brand new alternator? Please help me out.
