SOLVED - Digital pin not going high after being connected to level converter

EDIT: I figured out my problem. LV1 and GND were shorted. Whoops.

I am having issues using this 5v to 3.3v logic level converter. I have hooked it up as follows (forgive the lack of schematic. What do you recommend as a quick and easy way to put a schematic together?)

Pin 3 >> HV1
Arduino GND >> GND
Arduino 5V >> 5V
External 3.3V >> 3.3V (external because I will be powering multiple rfid boards and the on board 3.3V is not enough. The external supply and Arduino have common ground)

I am testing with this sketch:

void setup(){
  Serial.begin(9600);
  pinMode(3, OUTPUT);
}

void loop(){
  Serial.println("high");
  digitalWrite(3, HIGH);
  delay(2000);
  Serial.println("low");
  digitalWrite(3, LOW);
  delay(2000);
}

When I don't have the level converter hooked up, pin 3 reads around 5V when high, so I'm pretty sure nothing has been fried on the Arduino. When I do hook up the converter, pin 3 reads at around .25V when the pin goes high. What might cause this?

Does that mean that the issue is solved? If so, you can edit the thread title to say so.
