Attacking Mid is on a distinguished road
Generally, what fails first on these alternators is the voltage regulator brushes. You can buy a new VR (or even just the brushes) for a fraction the cost of a new alternator and probably buy yourself a lot of miles. Andrew Wynn has a thread showing how to replace the slip ring if you want to really do it right, but it's probably more work than most people want to tackle. I just put new brushes in my Valeo when it failed. I don't expect to own the vehicle by the time it fails again (maybe in 50-75K miles?)
