Tapping to the internal race can problems The brand new bearing. Upcoming, get rid of the stator from your rear 50 percent in the alternator. The three output wires of your stator bolt towards the rectifier assembly on Delcotrons and a number of more other other alternators. On some other alternators The three wires are soldered to terminals or possibly a circuit board. Up coming take out the brushes, voltage regulator (if It can be an internally regulated alternator: most are currently), regulator diodes (the triode on Delcotrons and a few others), plus the rectifier diodes.
