Squareback Connection to Electronic VR

Making repairs to engine wiring harness. When I removed the tape from wires I found that there was one wire from field terminal of alternator to F post of VR and one wire from second field terminal of alternator to I post of VR. Neither wire was wire was connected to ignition side of ballast resistor. Thought one of the wires had to connected to wire that was hot when ignition was on.
What are consequences of the way this was wired?
Both field terminals on alternator are isolated.
