    has photos of an alternator with 4 connections for windings (each of 3 phases
    + common), and the 8 diode rectifier. But wiring diagrams show only 3
    connections and 6 diodes.

    Where does the common winding terminal connect (there is a connection on the
    rectifier plate)? Where do the other 2 diodes connect?

    I handled one of these disassembled units but didn't have time to ohm out the
    connections.

    Thanks.

    common to the chassis
    3 big diodes to battery positive
    3 small diodes to the altenator regulator
    another small diode between the regulator and the altenator light,

    eigth diode, dunno.
