My battery indicator light continues to come on when I start my car. It stays on afterward until i start driving then it goes off. I replaced my battery 1 year ago. Could this be an altenater problem or a dash malfunction?

This indicates you have an issue with your ABS control unit. ABS is a system that "pumps" the brakes in rapid succession to prevent wheel lockup during an emergency start. A common cause of sliding in wet weather, etc. To do this a computer control module uses plungers to open and close the brake fluid flow to the brake in miliseconds..so while you are pressing on brake pedal hard... the system is actually applying and releasing the brake in rapid succession (miliseconds) to prevent skid, etc. When teh computer module goes bad the ABS and Parking brake light will stay illuminated. There shoudl be an ABS fuse in your vehicle (please refer to your manual) that can be removed. Remove this fuse and check it for dirt, blown, cracks, or corosion. Replace the fuse and listen with the motor off if you hear a hum noise this would indicate the motor is running continuously for the brakes and is another indicator of a bad control. With the fuse removed both lights should stay continuously lit. If the motor is running continuously this can blow the ABS motor.. your brake system will still function with the fuse removed, but test it with a slow roll (no gas hand pushed car) The ABS controller is quite pricey to replace in the vehicle and should be referred to a licensed facility such as a dealer. YES dealers are high but to have this job done properly you need to have the vehicle raised on a platform. Your local brake shop, muffler shop, shadetree wont be able to do this control repair properly.
Have you changed the fuel filter? If your battery has power in it it is not the alternator. If the alternator is not charging the engine will become slugish as the battery power nears zero and the light will become dimmer and dimmer until they go out.
Take out the air intake tube that goes to the throttle body and start the car. Now have someone hold the gas peddle so the engine stay at 2500 rpm get a can of carburetor cleaner at your local parts store and spray into the throttle body. Car may shut off start it back and repeat process until half of the can is left. reset engine light
