I just bought a brand new axe. When I turn on the gun the board lights up red, then rapidly blinks green,yellow,red and then shuts off. When I disconnect the board and turn it on it blinks red then green and seems to work fine. Only when it is connected to the body does it not work and shuts off. Ive replaced the battery, checked the solenoid connection, tried to reset the board and solenoid and the solenoid does not click (since the board just shuts off). what do i do?
