The wires on the solenoid of my LCD matrix have broken off. I can solder them back on easily enough, but I'm not sure which wire goes to which terminal. Both of the wires are white, so I can't tell which is positive and which one is negative. If someone can post a closeup pic of the solenoid with its wiring, that might be all I need.
Also, anyone know the voltage of the solenoid? I want just hook up a power source to make sure it's working.
Thank you to everyone who contributed. I just wanted to let you know that after resoldering the wires and shrink tubing around the solder joints, I plugged it into the frame and powered it up and I can hear clicking when I pull the trigger, so I think the problem is fixed.
