4248 Haunted alternator
Evening, friends.

My old alternator was on the way out for a while and it finally bit the dust a few weeks back. I got a new one fitted at a garage that was recommended to me, but ever since then my lights have been flickering when the engine is running.

I measured the voltage on the battery with the engine running idle and it was pulsing between about 13.5 and 14.5 V. It also seems to be tied to the engine temperature, as it becomes less noticable when the car has warmed up. Tonight was a cold one and my power steering wasn't working until a few minutes into my journey. I've had the same thing before I got the new alternator, but it came on with the red battery warning light on previously.

Earlier I tried swapping the battery out with a new one, but that didn't seem to fix anything. Does this just sound like a loose connection somewhere, or a bad ground?

always suspect ground, when things get weird.
Also worth checking the connector on the back of the alternator - if it's a 3-pin crimp one, they can fail quite subtly, and any discontinuity will fuck the alternator quickly, as the voltage will spike if the load vanishes.
