Answer 1

P1464 A/C out of self range test

P1536 Parking brake switch circuit

These 2 codes come from running a self test. Using key on engine running, To begin with you should not have the A/C on.And the brake should be step on then released, you are not suppose to keep stepping on the brake pedal. As for the battery light still on , after the alternaor replacement, check that all connection are in place
