Q: if you jump start a car and it shuts off as soon as you take off the cables is the alternator bad

asked by on

same as the question
My car has an automatic transmission.

Hello. Yes, a car that shuts off as soon as the cables, or power source are removed can indeed be an indicator of a bad alternator. I would remove and test the alternator before replacing it just to be sure. If you need help with this, feel free to reach out to a certified mechanic who can test your alternator and diagnose your dead battery symptoms in order to get your car running again.
