Abstract: A planar, rectilinear separator member is used to form a wiring harness for a rectifier assembly of an automotive alternator. The member is provided with pairs of upstanding posts spaced apart just less than the diameter of a conductor. A conductor is engaged and retained between two pairs of such posts. The member is further provided with a passageway located between the two pair of posts for the conductor and a "U" shaped terminal portion of the conductor passes through and extends beyond the passageway when the conductor is retained between the pair of posts. The wiring harness is formed of three conductors and one member, there being two pairs of posts and a centrally located passageway for each conductor. The ends of the conductors extend beyond the edges of the member different lengths and are connected to rectifier diodes carried on two rectifier plates.
