Is the alternator chargering correctly? What does the volt gauge on the dash say?

I only ask caz when the fusable link was on its way out on my Q half the central locking didnt work, the battery would go flat and my volt gauge would read higher.
The alternator was running everything while the car was running but the battery wasnt getting charged properly

Voltage is all good, I am trying to find the central locking control box. Has anyone got a idea where it is?
