For the cost of parts and the hassle of a teardown and rebuild, I'd just swap for a rebuilt alternator. I used to repair all the alternators that needed it in my shop, but labor costs and warranty concerns finally made me switch to reman units. Inside that alternator, there's a set of brushes, a brush holder, brush springs, a diode trio assembly, a regulator, a RF noise filter capacitor, and a 6-diode rectifier. Any or all of these components can cause a no-charge situation, plus the two major components, the stator and rotor. Then, there are front and rear bearings to consider. A remanufacturer checks all these things, repairs or replaces what's necessary, bench tests the alternator, and sells it to you, nice and clean, for under 50 bucks exchange in most cases. Hard to beat that deal!
