While driving at night, my battery and break light came on on the dashboard. About 50 minutes later, my car can no longer travel faster than 5mph. The engine was not able to rev up when it is in Drive, but it was able to rev up the when I put it in Park or Neutral. Finally it died, while traveling at 5mph.
Had a friend jump started the car, but was not able to travel over 5mph. Then it died shortly.
So is this the alternator? I’m hesitant to think it is the alternator, because the engine was able to rev up when it is in Park and Neutral.
