Version 2 Mechbox Extra Wires ?

Razcal · January 31st, 2009, 14:17

I have recently ordered a drop in version 2 mechbox for my TM SR16. When i opened the box i noticed right away that there are 2 extra wires. That would make 6 as opposed to 4. Does anyone know what these extra wires are used for?

My Assumptions -

To Battery
Grey wire with Black End
Grey wire with Red End
Red wire Black End

To Motor
Grey wire Black End
Grey wire and Red wire connected together with a Red End

What make of mechbox is that? I've never seen it before. :| is it possible they've grounded the connection???

Its a "System Version 2 Mechbox" from Huang. Also, the two thick wires going to the stock are a dead short whether the trigger is pulled or not. Im confused. I have sent Huang a pm and am waiting a responce.

Maybe they're wires meant for a MOSFET that are misplaced a little bit?

When i install the mechbox ( which fits perfectly ) and ignore the extra small red wire i get full auto fire as soon as I attach the battery. No pulling the trigger. Has anyone seen this before ?

I've seen things like that several times. Once was a jammed trigger contact due to poor manufacturing specs (was a JG) and one was a pinched wire in the mechbox that split the insulation and shorted it out against the mechbox shell.

My opinion, open er up and redo the wiring completely.

Newer JG guns are coming with MOSFET's pre-installed....could be that...

You can't ignore the extra one. connect it and it should work. I just installed one today and it works perfectly.

What do i connect it to ?

Razcal · February 3rd, 2009, 21:23

Just in case anyone is interested, the mechbox was shipped with a piece missing, which explains all this. After talking with Huang he sent me this...

Re: Mechbox
FET circit with connector is mailed to you.

So i will update this thread when i receive the missing FET circuit.

This is the whole set.

What is a FET circuit???

Yep, those are the new JG gearboxes with ball bearing bushings. Anyways, those wires that goes into the motor is freaking long.

That third grey one that's coming out where the motor wires are not supposed to be there. The need to be connected to the trigger switch.

See here.

Holy crap. JGs come with FETs now? Crazy...

My mind just blew a little.
