Can someone conceptually explain the generator regulator spec that states "Reverse Current To Open-Amps".

The reason I ask is this: I converted to Pertronix with a relay, everything works fine. Except (there's always an 'except') when I turn the key to the 'off' position the car keeps running. This is being caused by power back-feed through the Armature terminal going to the GEN light in the dash. My question is regarding the "Reverse Current" spec. Is the generator regulator working properly.

Someone suggested "Generator regulators contain a solenoid to disconnect the generator from power and the switch, which prevents back-feed." Looking for feedback on the spec before I buy a new generator, or install a diode.
