On A few other alternators The three wires are soldered to terminals or simply a circuit board. Upcoming remove the brushes, voltage regulator (if It is an internally controlled alternator: most are these days), regulator diodes (the triode on Delcotrons plus some Other individuals), and the rectifier diodes.
