Check the voltages on the voltage regulator (the black square with 3 pins). Make sure one pin is ground, one is 12V, and one is 5V. And, make sure the regulator isn't getting too hot - it should be warm, but if it burns your finger, then there's a short somewhere.

Does the power LED turn on when it's in the car?
