Start the engine and using a digital volt meter check the voltage at the battery with the engine running. If the alternator is good you will read from 13.5 to 15.5 volts DC.

If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good. If it stalls and dies as soon as you unhook the battery then the alternator is not good.If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good.

Battery light stays on in your Chevy silverado 2005?
test the voltage on the battery first, then on the alternator. If its good then it could just be the diode in the alternator. I would suggest you replace it becuase eventually your alternator will die and the battery will not get charged leaving you stranded somewhere. It is possible to just be a battery but you wont know unless you have the battery tested. check the voltage on the battery and the alternator before you do anything else.
