Wiring Question

[delta76]

I've opened up a G&G Gr-16 carbine and run into a problem. The gun has a nun-chuck handguard battery therefore the wires both feed through the mechbox from the same side and one wire is forced to cross in the path of the pinion gear in order to enter the pistol grip. This was obviously the stock setup though I never made note of exactly how the wire was run across. In this position, not only is the wire subject to direct wear by the pinion gear but it gets in the way of proper motor adjustment (the motor gets caught on the wire and cannot be properly adjusted up or down). I tried re-routing the wire through the same hole as the other wire but this clogs the pistol grip on one side and doesn't allow for proper adjustment either. Any ideas as to the stock route of the wire or what I can do to prevent the wire from coming into contact with the pinion gear? I know this sounds simple but I'm at a loss right now and can't think of anything.

That's because your pistol grip is too tight, so I suggest you buying a Magpul Miad or MOE grip... they have plenty of space for the motor and the wires

There should be enough room for that wire not to interfere. make sure you push them all the way down into the slot. The pinion gear should be able to pass right over it as long as you're not using huge, thick wire (I assume the wire itself is still stock). Actually take a screwdriver and force it down, don't just use your finger.

wires to the motor go through both holes. one wire is routed straight while the other crosses over so that both come down the same side. I forget if it's front or back but it's the longer one of the two that ends up coming down the opposite side. There is enough space between the top of the grip and the motor (near pinion gear) for the wire to cross. It doesn't get in the way of the motor whatsoever.

For a front wired M4, the wiring is typically like so:
1. Negative (black/-ve) wire. One end is in the battery connector in the handguard...the other runs under the outer barrel around the hopup unit, into the front of the mechbox just above the safety arm, past the trigger, down through the slot, past the hole where the motor would enter and out through the bottom (rear hole). Tuck the wire in tight against the mechbox shell, and as low as possible around the bevel gear area.

2. Positive (red/+ve) wire. One end is in the battery connector in the handguard...the other runs beside the back until it get's into the mechbox. Then it is typically attached to the upper switch contact.

3. Positive (red/+ve) wire. One end is conntected to the lower switch contact, runs along the slot (on top of the -ve wire), and out through the bottom of the mechbox (forward hole).

If I recall correctly, the red wire is 6.5" long from the bottom of the mechbox to its tip and the red is 5.5" long (might be 4.5"...but I think it's 5.5"). If you are running new wire and want to be really sure...mount the grip before you cut the wires to length, route the wires, install the motor and cut the wires to length.

Or....you can just google this yourself next time...took about 10sec to find this picture (it's from DonP's website)

Thanks a lot sorry for the bother
