Suggestions:
Refit everything again. Heck, double check the tightness of all connections. If you have to -- manually take out and reconnect any wires, cables, etc that you can without breaking them.
Next, look for damaged circuitry. Identify any broken parts by closely (takes about 10 minutes) looking over the circuit board with a magnifying glass.
Last, look for damaged or chaffed wires, etc.
Good luck man..
