Mp5 help

[Wolfz]

So recently my mp5 broke, and I've been trying to fix it. The problem is that it will fire once or twice before it just stops all together. I'm guessing its an electrical issue. I opened up the bottom of the handgrip and pushed a loose wire back on to its peg (it was the black wire if it matters), and it worked flawlessly for about a day and then went back to the same exact problem, occasionally not firing at all. Anyone know what I need to do to fix it? (It's not the battery, I put the same battery in my other gun and it worked fine).

You had fixed the issue when you reconnected that (black wire) motor connector back onto the motor lead. Make sure it's on there secure!
to not have this problem in the future, get some pliers and clamp down on the connector (again, the one attached to your black wire) and squeeze to make it slightly flatter.
After that, plug it back onto your motor. You should notice that it's harder to get on, but once it is, then it should be nice and secure, and not pop off on you again.

Thanks, looks like that was the main issue. I had my dad help me out with it and we actually figured out that it was a bad connector and he fixed it for me.
