Uprated my alternator to a 100A one - nice & shiny and also charges the battery!

What should I do with my old 65A Alternator? I know the brushes are broken (I had to take it apart didn't I?) and probably the regulator. I assume I can replace those parts - is it worth a refurb?

I would not waste the money, chuck it in the garage and in a year or to when you find it again, down the tip with it!

Is the new one a 'quality' nice and shiny one? If so the bin the old one in a few weeks time once you know the new one is running ok. If its a cheapy one and the old one was a quality one it may be worth a rebuild (less than £20 for some kits), then put it on the shelf and wait.

The consensus appears to be "wait and see". The new one is a Denso alternator which has good write ups. So into the box at the back of the garage it goes...for now!

Keep it. The rear bearing on 300tdi alternators has a nasty habit of seizing. Where I come from, a few auto electricians have the means to fit new bearings but that means removing the alternator, finding a means of transport to take it for repair and spending a day without a vehicle. If you have a spare alternator (even if it doesn't charge the battery), you can fit it and use the vehicle for a few hours. I bought a spare alternator to carry with me when I travel overland just in case the bearing seizes up.
