So I got my new pistol grip for my m4 and installed it, only problem is now is that my gun is not firing. I cannot find the right way to hook it back up. I have tried s lot of different ways but all failed. The battery works but the motor just does not turn or make noise when I pull the trigger. Anyone got any suggestions?

If neither of those fix you're problem I'm sure my favorite Gun tech T6e9a could offer some suggestions as well as possibly fix your solution when he gets back. Hopefully it is just a wiring issue. |

Try connecting the motor outside of the pistol grip, connecting the battery, and pull the trigger. Make sure to either hold the motor or have it secured somehow so that it doesn't spin and cause damage to the wires/motor connections. Now if everything is hooked up properly, the motor spin.
If the motor spins, it will be an internal GB issue.
But if the motor doesn't spin, it will be battery flow not getting all the way through the wiring. This could be result of a pinched wire, or even a few tabs that are bent down a little too far that they don't complete the circuit. But if it was just installing a new pistol grip, it woul probably be a pinched wire. In which case, I would take the grip off, and inspect the wiring and make sure there are no wires getting stuck between where they come out of the gearbox, and the pistol grip. Also want to make sure the each wire went through their correct holes, and attached to the proper connections on the motor.

I'd either have to say since all you changed was the grip, would be either there's a pinched wire or when you install the heat sink that one of the wires is most likely popping off. I doubt there's an internal GB issue if it was working before and all you did was change something cosmetic.

Sometimes the motor connectors like to slip off the terminals in the motor like Mayhem said. If that is the case you can gently squeeze the connector with some pliers so that it fits a bit tighter. This happened to me a while back and I took me forever to realize.

Yes, I must second that as something else it might be. I myself have had that issue. Such as when you tighten the base plate, after setting the wires, the plate doesn't always keep the wires right in place, and since everything and be slightly tensioned, in the grip, the wires can pop off.
In which case, as just stated, just carefully, I repeat, carefully, crimp them a little more. I you over do it, it shouldn't be the end of the world, just stick a small flat head in it and pry it open slightly, enough to fit where it goes on the motor.

Ok fellas, I tried everything you mentioned and all I got were a few motor turning sounds and that was it. Anyone know anyone in the thumb area that could fix it?

Are you running the wires both down the rear of the grip correctly? I fixed a lot of issues where people tried to run one wire down the front and the other down the rear of the grip. The motor will jam against the wires and not seat correctly. Normally the positive wire is longer and exits closest to the trigger. That wire needs to be run around the motor shaft and down the back of the grip while the negative wire is run straight down. If you ran them down front and back and forced your motor in you could have pinched or cut one of the wires. It is also possible to cut the positive wire when removing the motor from the gear box. If you had to use pliers or force out the motor there is a chance the pinion gear caught the positive wire on the way out. You can use a flash light to look into the pinion hole and check the positive wire for insulation damage.
I second that you try running the motor without the grip on to see if it will turn over outside the body.

Well here is my solution, I bought G&P 120 motor and rearwiring deans with gaurder high speed gears to boot! I think this was better for my gun anyway and I wanted to move to deans at some point because I have yet to hear anything bad about them. Thanks for the help guys!!
