If the power in my car keeps cutting out would it be my alternator?

Question

2 weeks ago all the power in my car died for about 2 seconds. My headlights, stereo, dash, everything power went out and turned back on. This morning on my way to work within about 2 minutes everything went out about 15 times for 2-3 seconds each time. Does it sound like an alternator problem, or something else?

Answer 1

it's your alternator if you car is in motion and this is happening... if you just cant start your car, it is  your battery

Answer 2

it could be your alternator or battery connectors or even your battery.  

Answer 3

If the car keeps running when it happens, then it's not the alternator. It's a loose ground wire under the dash. If the car is a G.M., the wire is probably to the lower left under the dash. Try feeling around underneath and if that's the problem, it will be obvious when you find it.

Answer 4

If the problem is happening while the car is already started and in motion, it is probably the alternator.  Get it looked at now before it strands you somewhere!

I'm not a mechanic, just a guy who's had his share of bad alternators.
