Mmm. That could be something internal then. Start with something simple though. With everything switched off pull the wiring plug off the back of the alternator and thoroughly clean the contacts. Replace and see if the problem goes away.

If not start thinking about how old the alternator is? Brushes can be changed easily and slip rings can get dirty and need cleaning. Otherwise you could be looking at replacing the diode pack. If unsure about doing this then have a local auto electrics place check it out. Peter.

Thanks for that, I think a likely culprit cud be the terminals or diode as had similar problem before, wondering if proximity to the exhaust manifold could be a factor in failure . Hope to check over weekend.
