Well, I finally got around to disassembling my alternator. There was a small amount of the carbon based sludge around the brushes and slip rings. One thing I did notice though and is significantly different to my original alternator is that the "disc" inside the alternator behind the pulley is all rusty. So I am wondering if the alternator has gotten wet possibly?
Re-installed alternator yesterday morning. Blimey it was cold. Didn't get much further as on inspecting the drive belt it's starting to split, so will replace that whilst it's all apart.

Did you fit a new regulator/brush pack to the old alternator or fit another new alternator?

I fitted a new regulator/brush pack to this alternator. The slip rings were ok. So fingers crossed it's going to be ok. There wasn't a great deal of the carbon based sludge.
I still have my old original dead alternator where the slip rings have a piece of the copper plate missing from them.
I did wonder whether it was real copper plate or whether it was something along the lines of this:

Don't know if your joking or not, but will be solid copper. Not copper plated. Just a poorly designed alternator which doesn't allow debris to get blown away.

There's a wealth of information on the Web concerning alternator re-conditioning, including slip-ring replacement, which doesn't look too difficult if you can use a soldering iron. Replacement parts are surprisingly inexpensive and if I had a spare "dead" alternator on my hands, I would be tempted to have a go.

18 months ago when i saw the slip rings had copper missing, I just assumed it was something that was terminal and went and bought a new alternator. I'll have a look at reconditioning the one I assumed was "dead". Cheers.

Wasn't joking, I really did assume they were copper plated, due to the layer of copper appearing to be so thin and whatever occurred in the alternator it had managed to strip it off.
It may not be to much of a problem fitting a slip ring and regulator to an old alternator. The only issue is the hours fitting it and hoping it works afterwards, unless you can find somewhere that could test it for you before fitting it.
Thanks for the link Simon. Yes, it's not an easy task to take the alternator off and put the reconditioned one on just to test! I'm sure I can find a local auto electrician who would be able to bench test one.
Cheers for the advice all! I may well have a crack at resurrecting my old once assumed dead alternator after I've got my C back on the road.
