You dont need a new board. Check to make sure that your grip screws aren't chafing against the wiring and causing a temporary short.
Heres what you can do to ensure its not the board:
- Remove the board from the frame.
- Examine the board for any damage in the area near the grip screws.
- Check the capacitor for damage (I have seen this especially with those who replace their screws and unknowingly use screws that are a little too long or use excessive force when tightening the stock ones).
- Check your battery connections.
- Attach the battery and power it up.
- Cycle into your firing modes and select FULL AUTO.
- Press and hold the trigger switch.
If you can hear the solenoid clicking or see the LED blinking the board is fine and the problem has to do with the grip screws shorting into the board or one of the wires.
