If your alternator has been giving you trouble recently, the only real solution is to have it serviced but you might be able to
jumpstart
your car.
The alternator keeps your car battery charged, and if faulty, it can prevent the vehicle from starting. Some common signs of a failing alternator include:
  • Flickering, dim, or overly bright lights
  • A consistently dead battery
  • Slow or non-working accessories like the radio or power windows
  • Frequent stalling
  • Whining noises
  • The smell of burning rubber
  • Battery warning light on the dashboard
The only way to start a car with a bad alternator is to jumpstart the vehicle. However, the car may shut off after only a few minutes, so you should avoid major roadways and get to a
mechanic
or safe location immediately.
If the failing alternator has left you stranded by the side of the road, you probably realized how beneficial a roadside assistance membership is.
