Hello I'm new to this forum and would be grateful for some advice on where I might find an ABS pump/system my ABS light is constantly on. Also I think the alternator has packed up as not charging battery. Any advice very much appreciated thank you

1998? is that the CC or the year? a 1998 is a 5th generation. Big headlights, the best looking one

You can short out a diagnostic connector behind the dash/radio area in order to get the ABS flash code. The ABS light will then flash a certain number of time (slow flash for 10, quick for 1). The flash code will then tell you what its not happy about. Plenty of videos on youtube for this i'm sure.

It could even be low battery causing the ABS fault.

As for the alternator - check the belt is tensioned, check the connections are decent. Check the battery is decent and its connections. Check the main earth straps and check the main wires are not brittle. If the alternator is duff you can get a new one or have it rebuilt easily enough. Use a multimeter to check if the battery voltage raises to approx 14v when the engine is running. If it doesn't, the alternator isn't doing its job...

Hi and welcome. Have you got to the bottom of this yet?

Definitely diagnosing the trouble code is the place to start. The OEM service manual can be downloaded and tells you how to get the codes and what they mean.
