Hey guys, figured I'd make this post and see if I couldn't get some help from the fans who are a little bit more active/savvy in the tech side of things. I shipped my TM M14 off to a fellow member of this boards and now it appears as though he's having some trouble. When he fires the weapon (Or, attempts to rather) all he gets is a click for a response. The weapon doesn't actually fire. Now, I thought at first maybe it's because he had an 8.4v pushing what a 9.6v should be doing as far as the motor is concerned, so I asked him to charge up the 9.6 I sent with it and give that a try. Same results.

So first I tried to see if it wasn't the gearbox that pooped out on me, so I asked him to loosen up the spacing between the gearbox and the motor and see if it still turned, he says it does. Now I asked him to fidget around with the spacing and maybe get that part right, and so far he says he only hears the click now. So in short I'm wondering what could this possibly be?

I asked him to check out the weapon for any missing/stripped teeth/spurs as well as check the piston to see if it would move on its own will when the spring is pushed back with a screwdriver, all with positive results here.

So AirsoftSniper, I ask you what could he possibly do to get this weapon back in the fight? Or what do you think is not right with this situation?

So he took apart the gearbox, reassembled it, and it's still having this issue? Initially my first thought would be the piston is locked back, generally because of a faulty shim job, and less likely because of a dying battery. However, if he took it apart, that's likely not the problem.

If it's making a clicking noise, the motor is getting power, which means the wiring harness is good, which leads you to an issue with the motor, likely it is either not getting enough power, is over-tightened into the gearbox, or the motor itself is failing. Something to check would be a the motor brushes, but aside from that I don't know very much about motors.

I had this problem with my M14.

I could not find the problem and still to this day dont know what caused it.

What I did to remedy the problem was break down the GB completely... Clean it... then Rebuild it.

I have not had this problem since.

I know that doesn't really help in diagnosing the issue but that's what happened to me.

Sounds good guys, thanks for the positive help. I'll let him know what we came up with and see if we can't get the problem resolved.

My honest belief it maybe the gearbox wasn't put back together properly. Because not even two months ago I was using it at games here in SoCal, and up until the gearbox locked due to me firing the weapon (Or attempting to, rather) the spring locked back and I said if he reset it that it should fix the problem.

Thanks for all the help, if you guys can think of any more solutions feel free to post it here, so we don't have this sort of problem again, or rather, the answer is already out there.

Get him to put the highest rate Mah 9.6v fully charged battery hes got on it.

If that doesn't shift it its defo a seized gearbox, which in an M14 is going to be one or a combination of the following.... pants shim job, missing teeth on gears/piston.

Thinking about it it could also be something as simple as sh1ty contacts on the electrics reducing power to the point its not enough to turn the box over, similar to what dutton was on about with the discharged battery :-/

I had this kind of problem on an MP5 once, check to make sure that the contacts on the motor a connected properly (red to red, black to black) you know, also with what vindicareassassin was saying, re-solder the deal. A few more things to check are the fuse, and the actually trigger contacts them self. Basically anything electrical. Hope this helps, and yes this is my first post so if I am doing anything wrong tell me and I will gladly correct them

Maybe be a little more descriptive of the clicking like is the trigger clicking when you pull it or is it like the gun wants to turn but cant? If it's the trigger then you have an issue with the trigger mechanism. If it sounds like the gun wants to turn but cant then you either have:

Battery problem: not enough power or bad battery
Shimming problem: not done correctly
Motor: maybe took a poopoo
Bearings: might be going bad, I had something similar happen on a V2 couldnt figure it out till I realized one of the bearings seemed a little odd

If it locked up on you when you were using it either the battery was low or you've got some other issue. AEGs just don't lock up from shooting them so there must be some internal issues. I hope this helps in some way! Post up when you figure out the issue!
