I posted a reply in one of your other posts, but the answer is, the loose wire SHOULD go right to the frame of the power truck via solder or screw-and-terminal. It MAY not, if there are wiper contacts involved. It all depends on the design. But I'd bet it just attaches to the engine or frame somewhere.
Your first diagnostic test is to ascertain which side of each truck picks up the power. And then make SURE they are NOT on the same rail. At that point, you can apply power to the track, and touch the loose wire to the frame of the powered truck, and it should move. Look for a screw hole somewhere that it might have attached to. These engines are pretty basic, it's not rocket science, you just have to remember the trucks pick up power through one side only on these old units, and so they MUST be on opposite rails. One side of each truck has a insulated wheels, and other non-insulated. Make sure they're on opposing rails.
Sometimes people take the wheels and axles apart, and they remount them incorrectly so the insulated/non-insulated wheels aren't in alignment, or are on the same rail. That could also be a problem. You can touch the motor leads directly, to make sure the motor works, then if it does, put both trucks on the track and do it again. If it sparks and doesnt' move, one truck needs to be turned 180. If it still doesn't work, then perhaps one axle was incorrectly installed, and it's shorting out, so you need to look at the wheels to see where and which side the insulated wheels are.
Like I said, not rocket science, but you have to understand how they operate. Good luck, let me know if you need further help.
