GM Alternators
My rewound CS-144 alternator identifies as a Mopar alternator, because it's in one and I wrote Mopar with a black sharpie on it before I painted it matte black.
It not a 1-wire. It senses voltage at the battery that's mounted in the trunk, puts out 115 amps at a slow idle and peaks at over 250 amps at a fast idle. It also has an externally mounted HD Bridge Rectifier and bolts right in with a simple bracket change.
Been to some pretty big shows with the car and no one has ever noticed.
