I was on my way to work on wednesday morning (5am) when the 'charge' light came on, "oh damn and blast!", I thought. Stopped to check, the belt was still running so must be the alternator. The history of the old Gal we have, is that it has done 180,000 miles, is a 'bit' bashed, and the alternator that was on there had the old 'box of budgies' rattle since we got it. Popped into Partco and collected a new alternator, fitted it in 1 1/2 hours, like a new motor!! You wouldn't believe how quiet it is! For an old engine with 180,000 miles, it sounds like new! I checked the old pulley (clutch type) when I removed the alternator and it was seized solid on the alternator shaft, the new one worked as it should. No wonder it was chirping. Replacing an alternator on a MKI diesel (110) is a piece of cake, as long as you remove the airbox, engine cover, etc (don't forget to disconnect the battery!!!) One online company I checked prices and availablity with said they supplied new alternators but with 'solid' pulleys, due to the failure rate of the clutch type. Sounds great but saves them
