How long can you run a car without an alternator?
- tdawfik123 8y agoI had to do this once. Blown alternator, dead battery. Luckily had a backup battery and it got me home 10 miles away.
- eesmith 8y agoI had the alternator fail on me while driving, though with a working battery. It was at night and I made it about 70 miles, mostly on the interstate. The headlights were noticeably weaker by the end. That was in line with the estimate of 3 hours at the end of this piece.
