Not right away. When the alternator goes out, there's nothing on the car to generate
electric power, and everything electric in the car starts operating from what's stored in
the battery ... spark plugs, cigarette lighter, radio, brake lights, power windows, etc.
Once the battery is run down, since the alternator can't keep it charged, everything
electric begins to die, starting with the current hogs ... starter, headlights ... and moving
down to the low-power devices last ... interior lights and radio.
Charge your battery!It also sounds like you might have an alternator problem.
THE BATTERY WILL GO DEAD
When a cars headlights, AC, and radio are losing power, it is possible the alternator.
Get a filter for your alternator. What you are hearing is alternator noise in the speakers. You can purchase these at a Radio shack or electronics store to take the alternator noise away.
I'm not exactly sure, but I have the same problem. My alternator was replaced and my radio does not work either, but the light comes on. Someone told me we have to go to the dealership and get the code put back in for the radio to work.

Ignition coils can go bad with age. They can also be damaged by a bad alternator putting out improper or unclean voltages.
CHANGE YOUR VOLTAGE REGULATOR DRIVE SAFE It might also be a good idea to go get your alternator checked. Autozone/Advance Auto do it for free.
Get the alternator checked before your battery goes dead.

if i remember correctly you have a heavy duty cable that goes to the battery and a light cable typically red that goes to ignition posative via the charge indicator light and some alternator have a earth wire as they are insulated this varies from make to make of alternator and vehicle maufacturer but the principle is the same
you have to go to the radio station, and ace the test, then she goes back
