ICS MP5 A4 dead, need help and diagnostic

[lizbob]

Recently I turn the screw for the motor adjustment to try to enhance the sound of the gun, it was strange (one full turn). I shoot with the gun for half a mag and suddently it stop firing and the trigger was jam. I retreive the mag and I saw a BB in the feedind tunnel. I shoot without the mag and the BB fly away. I try again with the mag and the same problem occur. Since now the gun refuse to shoot, no motor noise, dead meat...

The barrel is not obstruct, the Hop-Up is on the lower position, my battery is full, the fuse is ok, but nothing happend. Anyone have a suggestion ? What step do you suggest me ? What should I try now.

Thank

well, you may have adjusted the motor too much and it is locked up inside the mechbox, I woudl try pulling the motor out and re adjusting it. Check for stripped/ damaged teeth on the motor gear itself...

Another issue that I recently dealt with was that we turned the motor adjustment screw too high and disconnected the power to the motor...

Both require minor assembly...

which way did you turn the screw? in or out? 1 full turns seems like a lot, but im no expert

Just to be sure, how I must re ajusting the motor ? What do you mean by disconnected the power to the motor, how did you fix it ?

Thank

There are two wires that connect to the motor, they are simply pushed back onto the metal connectors on the motor itself. This is done by removing the motor plate in the pistol grip.

turn the adjustment screw the oposite way then you did before to loosen it a bit and see if it starts going. Mostly sounds like a bad connection or a disconected motor. The motor would still sound like it's working even if it jammed. Check you fuse agian.

Effectively, I tryed to turn the screw the opposite way but it does'nt work. I'm going to check the connection and try to re ajust the motor by picking it down.

I keep you inform.

Thank you, I appreciate.

Finally, I opened the motor plate at the base of the hand grip, and I put in back on place, and now it's working. Thank you again for the comment, you help me.
