I rebuilt my alternator by replacing the bridge rectifier and voltage regulator this weekend. I had a little trouble with assembly after soldering the new components but that was user error, dummy me thought the spacer (that should go between the rotor and bearing) went between the pulley and bearing. . . needless to say it was locking up every time. Anyways, I took it to Oreilly's to have tested and it passed! Success! !
