Busch US-Style Crossing Signal Need Help

[Harrison]

I have a Busch US-Style Crossing Signal that I got serveral months a go. It was working then, now I am finally ready to use it, and it won't work. I connected the black to the middle and the copper to the sides of the flasher unit, won't work. I doesn't help that I lost the instuctions, and the little yellow pins that hold the wires in place.

Thanks in advance,

Looking at the instructions that Ulrich linked to, it appears that you may need to switch one pair of the non-black wires. That will allow the unit to flash back and forth, since when one light is one, the other is off.
