Double check that you made the wiring mods exactly as Bob outlined. If that is different than this then let us know: 1) Disconnect the RED and GREEN wires going to the voltage regulator; 2) Run a 12v+ wire to the S pin of the voltage regulator (the one that used to have the RED wire going to it and that you have now removed).

Repeat the test making absolutely sure the voltage regulator is grounded, use an extra ground wire with alligator clips to clip on to the VR itself, and see if you get the same results. If you do, replace the Voltage Regulator.
