The lads came to test everything with a magnetometer and found nothing magnetised! So sadly back to stage one, which is a royal pain in the arse. We have decided to fit a suppressor/filter on the alternator to try and chalk that one off, so I will hopefully see if that cures it tomorrow, as we realised that the engineer never fitted a suppressor on the new alternator since the last one went faulty. I have done some research with my friend Google and seem to think that it's some sort of electrical problem, bit of a head scratcher!
Cheers, Jim
