So after my fan refurb the car went straight off to the paint shop for some tidying up.
I therefore did not realise my alternator was not charging my battery. The battery light is not coming on but checking the voltage at the battery with the engine running im only seeing 12v.
So i need to whip the alternator off and see if i also have got my wires crossed!
Or could it be a faulty voltage regulator which i fitted? Its marked up as a Beru part bit it was very cheap off the internet. You do hear of fake components being sold.
So to clarify, the blue wire goes to the insulated terminal and the brown wire to the alternator chassis?
But shouldnt my battery warning light be on ??

Hi there, I had the same issue after my rebuild, the alternator not charging the battery. It's unlikely to be your new regulator, it's more likely to be the alternator itself.
I took mine to a local specialist and he diagnosed an issue with the rectifier, swapped it out for a new one, cost circa £100. Put it back in and all was well.
Mine did cause the battery light to illuminate however.

You are correct on which wire should be where, the wires on mine naturally sat the other way round when I fitted it, hence my mistake. I think the battery light was on when I had my wires crossed, but not 100% sure now.
Edit, just reread my post when I made the mistake, I think I would have mentioned the battery light, so I don't think it cam on with the wires swapped, but not 100% sure, sorry i can't be definite on that point.

So was my own stupid fault. Found the 8mm nut securing the main power lead rattling around inside the plastic end cap ! I mustn’t of tightened it up when I put it back together after doing the fan.
Charging now but only 13v on tick over. I have a single pull conversion so alternator running slower than standard so maybe that’s why ?

Ya wally  I have single pulley conversion too, I haven't checked to see what it charges at at idle, I may get chance tonight.

Some say don't, unless you take it somewhere that is used to doing magnesium. Loads of threads on it just to add to the confusion.

Yes AP90, I read and saw that..
I have just heard back from Tactical Coatings UK Ltd. and my Shroud has been Cerakote coated..  I really want to post the photo Chris there sent me, but I am going to wait until I have it in my hands and then take a [better!] photo of it.. But it looks awesome.. 
Just need to sort where, what and how I get the Fan painted..
I'm kinda moving away from the Powder Coating route..! Seems a little worrisome..?

It looks great, but........the fan coating gives a lot of unbalance and vibrations, I just coated the housing and polished the fan.

A somewhat timely thread. After some 'pinging' and slight rough running of the trusty 964 at constant speed and lumpy idle I've diagnosed the distributor drive belt has just given up

I got the Shroud back from TAC Coatings [http://www.taccoatings.co.uk/contact/] and it looks GREAT..!
Trouble is now I really need to get the Fan done too, as it will really show up next to/inside the Shroud..
So.. Zermatt Silver..? Who do I send it to..??
I was kinda thinking about sending the Fan to TAC and getting them to Cerakote it a lighter Bronze.. It isn't exactly a smooth surface though, so wondering if it'll make a noise/wind resistant whizz when spun up..?
