Hey guys, so my gun was shooting fine for a while, but now it's doing this thing where the blue light comes on, but the gun will not fire. It makes a really high-pitched noise but the motor will not rotate. The high pitched noise sounds like just the normal electronic ringing noise, like what you hear when a crt monitor would turn on. I've cleaned the optical sensor and the two holes on the sector gear. Before it stopped firing at all, it was shooting 3 rounds on semi and full, and the motor would start to pull for a 4th shot, but then it would sound like a normal version 2 gearbox without the anti-reversal latch. My theory is that the ECU is toast- do you guys have any thoughts?
