1. A generator comprising: a rotor structure having a rotor frame supporting an isolated rotor circuit having exciter armature turns, a rectifier assembly, and a first and second bus bar electrically coupled to said rectifier assembly such that said first bus bar is a positive voltage bus bar and said second bus bar is a negative voltage bus bar; anda resistive element electrically connecting said rotor circuit to said rotor frame. 2. The generator according to claim 1, wherein the rectifier assembly includes multiple diodes configured to convert an alternating current to a direct current. 3. The generator according to claim 1, comprising exciter armature turns electrically connected to the rectifier assembly and configured to energize the rectifier assembly. 4. The generator according to claim 1, comprising a stator within which a rotor is disposed for rotation about an axis, the rotor including the rotor structure, the rotor configured to induce an alternating current in the stator, and the resistive element configured to pass a current from one of said exciter armature turns, said rectifier assembly, said first bus bar and said second bus bar to the rotor frame. 5. The generator according to claim 1, wherein said resistive element electrically couples said exciter armature field turns to said rotor frame. 6. The generator according to claim 1, wherein said resistive element electrically couples said rectifier assembly to said rotor frame. 7. The generator according to claim 6, wherein said resistive element is connected to said rectifier assembly between an exciter and a plurality of rectifier diodes. 8. The generator according to claim 1, wherein said resistive element electrically couples said first bus bar to said rotor frame. 9.
