CM M4 firing issues

[Villid]

Ok, my buddy just bought a Combat Machines M4 and hes having issues with it.  Some of the Alphas from redfox last weekend may remember this.  After playing most the morning the gun began firing slowly.  Believing it was the battery, it was replaced, however the gun continued to fire slowly.  Changing the battery a second time had no effect.  Eventually it ceased operation all together.  Fuse was intact.  The next day, the gun fired normally, for approximately 2-3 hi cap mags before doing the same thing.  With out breaking open the gearbox, im at a loss for what it could be.  Any help would be appreciated.

Is the gun stock?

Could need a new motor, have you tested that?

[Villid]

yeah gun is stock.  hes tried adjusting the motor, but without a lot of success.

[Villid]

bump for still needing help

[BigMan23]

could it possibly be the wiring? It sounds like it could be a short somewhere, which would explain why it fires fine then slows down. And are you sure both batteries were totally charged? 

[GrimWulf]

What batteries are you using in this gun. Brand and size please.

[Villid]

yes both were charged because i used one of the same batteries in the afternoon game with no issue

8.4v Intellect 1200mAh NiMH
9.6v Tenery 1400mAh NiMH

Well the only G&G I have ever had did something like this. Turned out to be the G&G motor just wore out. If you know someone with another long type motor try putting it in there and see if the problem continues. It may be the battery but if it did the same thing with both batteries then I would check the motor as it is really simple to do. Good luck.

Villid, I have the same gun.
If you want to, I can take a look at it for you.

[Villid]

where are you?

[Vesper]

It is best to catch me during weekends.
I'm going to be in Simpsonville area, and there is where all my tools and guns are.

gun was fielded again this weekend, after we tried adjusting hte motor ourselves.  it fired for about 100 rnds before ceasing all function. 

[Vesper]

The most likely case is that the motor completely burnt out.

[Villid]

its ceased functioning during play before.  im considering having it rewired

Something is missing here, motors don't die and then act fine and then die again. Have an experienced tech do an actual diagnosis.
