A friend took apart his AK with the intention of learning how it all works. He cleaned it, lubed it, upgraded some parts. Then he decided to add a Bravo AMU #1, and the trouble began. After days of trying and failing to solder everything properly, he gave up. Now it's a year later, and he's given me the gun, disassembled, in a box.
To sum up my problem: I have forgotten how the wires from the motor and battery attach to the plastic trigger mechanism. Specifically where they attach and whether they need to be soldered onto it or clipped in place. Can anyone help?
