should I return the the new altenator? on 1990 Chevrolet Corsica

I replaced the bad alternator with a new one but the checks say the voltage is bad... Should I return the new one I put on the car and trade it for a different one????

Usually the auto parts store has a alternator test machine but its not uncommon for a rebuilt alternator to be defective right out of the box, If they have a test machine have them but it on there and see if its bad.
the Altenator was a NEW one not rebuilt
Even a new alternator can be bad right out of the box, have them test it to see if its bad.
Also check all of the wires and connectors for damage. Make sure the grounds are secure as well. Is the battery fully charged?
