When I fitted the other alternator yesterday the cat warning light came on and battery one so I swapped back to original alternator and it still has the lights on now any ideas

I started it with the belt off and it didn't do it so wandering if it would be the waterpump as it still does it with a different alternator fitted.

Unless you've got 2 dodgy alternators, the noise is likely to be coming from the water pump.
