I heatsunk it while soldering to make sure it wasn't damaged.
First of all use a multimeter to make sure the ends of your wire are actually connected to the big leads (just to make sure). Also make sure the big leads aren't shorted together somehow, thus bypassing the sensor alltogether.

Then try using the multimeter to read the voltage between the output pin and the ground pin as you pass current through the big leads. If your voltage changes but your input doesn't you have a problem somewhere besides the sensor itself.

That's all I can think of right now.
