Connect the board to your power supply again and repeat the current test. It should still be about 6mA.

Check the voltage across the two diodes marked here:
It should be about 2.5V, if not check for shorted tracks and solder bridges around the transistors.

If you've made it this far you should have a completed and working board ready for the driver coils. Repeat with the other 2 boards and you should now know which parts still need to be fitted to the partly built board.
