Are your heated seats On?

I find they cause the dash lights to flicker as the element cycles on and off.

I can't see thee being much difference in cost between a repair to your & A N Other ...... but do you know the 'new' one will be any better?  ;)  ;)

I'm sure that someone here will be able to fix you up with a known to be OK alternator for not much ..... but it'll still need fitting.  ;)

The best thing to do would be some diagnosis first. It could well just be a loose connection. The crimps on the battery terminals are a favourite.

...and check the earth strap?.... by the radiator drain, they can rot through sitting in water on the drip tray.

Kev has fine a very good diagnosis guide in maintenance for battery and alternator, with a meter.

Ime the 2.5 and 3.0 are quick to throw the warning light on if the alternator plays up. Its worth further investigation of the simple things like connections first. :)

The alternator warning light on the dash.

As said, earth strap, is down by the the radiator coolant drain. You need to stand by the battery, then look up from under the bumper. You'll see a braided steal strap, it sometimes rots through.
