A few other things you might want to try...
1) Measure the voltage at the connector when the 9v batt is connected
2) Measure the voltage at the power supply before you connect it to the board, and...
3) Measure the voltage at the connector after connecting the power supply
This will give you an idea of what voltage the board 'likes', and how the circuit is affecting the power supply voltage (i.e.: if the current draw is pulling down the voltage or not).
