BK Controller set up problem

You can try to resolder or attach this loose wire to black (negative) battery lead connector.

how exactly would I connect it to the black battery lead connector? It's not really long enough

Black wire sticking out of the ESC is right there you do not need to go all the way to the battery, sorry if I wasn't clear.

took the shrink wrap off and this is what mine looks like. Notice how the green is missing from the circuit board where the red wire is supposed to be soldered on? Where am I supposed to solder the wire...onto that little round metal part the arrow is going to in the picture?

I don't think it's so much of you not being clear as me not really knowing what I'm doing.
Sorry for all the pictures...but again I don't really have a clue what I'm doing so I want to make sure I do it right.

So I can take that lose red wire and solder it to the black battery lead that is coming out of the esc...like the arrow is showing in the picture?

Why you do that?, but you have done that...
It would be hard and as you noticed it doesn't stay there, so no.
Try to solder to black power wire which is on opposite side of ESC, but do not try solder to pcb unless you confident with your soldering skills. I would recommend to strip wire and solder far from ESC and heatshrink or tape it.

Yes, this is correct.

took the shrink wrap off because I thought I was going to have to solder it back on...already wishing I didn't take it off

So should I solder it to where the black wire is soldered to the esc?

Strip wire where white arrow points and solder there, it would be hard to solder directly to pcb.

-or if it helps try to solder to the brown wire (blue arrow) from 3-pin rx-cable, same ground reference.

Awesome...thanks man. I will do that tomorrow and let you know if that solves the problem

sorry, one more question...what's the best way to strip the wire in the middle like I need to?

Razor blade, two round cuts and one longitude cut.

well it appears the other jumper has come un-soldered aswell

Since the first one is going to the black battery lead does that mean the other one can go to the red battery lead?

Hold on!
What other jumper???
Do not apply any power before attaching picture. Do not solder in random order.

the red one that isn't being pointed to in this picture has now come un-soldered

I am just wondering what you do to the controller...
Send it back I will fix it and epoxy everything around, so you can pull entire truck by wires.
If anything this last, unmarked wire, must be soldered to the tiny SMD resistor, cannot be soldered anywhere else. But then you can crack it if not done properly, carefully.
