Went to get the Disco out on Friday morning for the wife to take to work before heading to the in-laws beach house, and the alternator was whining (note, different whine to the cold start whine, that appears to be the idler pulley, I did have the required 6203 2RS bearing in stock, but I need to find it). ****After work yesterday I went and checked the Landy, and the alternator isn't charging - 11.4V at idle, at 3000rpm 12.1V, all that with no load, turn the lights on and it's even worse. Whipped it off in case it was anything daft like a stuck brush, but it looks like the diode pack is fubared.
The offending alternator (including obligatory shot of a foot - it's still 25 deg C even at night here now, it's a bit warm for spannering)
Reading around the Discovery forums it appears a common failure mode, a whine one day followed by no charge the next. Obviously nowhere here stocks a Disco3 alternator nor the diodes, so we've just had to lump a considerable sum on the card to DHL an alternator from Rockauto, fingers crossed it arrives this week (last order got here in 3 days). Unfortunately customs are going to be dipping their finger in on this as it's over $200.

....and it would appear to be time for alternator #3 - 5 years / 40k kms later. Firing up the Disco 3 in the morning and greeted by loud whining from the area of the alternator. It's still charging (for now).. After work I'll take the belt off and make sure it's not a pulley, but my ears tell me it's the alternator again... That was a Bosch reman, but the only issue *appears* to be bearings. I reckon I'll try a BBB reman this time ($80 - half price on Rockauto currently) as opposed to $230 plus 30% customs fees, and source bearings for the Bosch.
