Ok, so I looked and I see a blue, I guess it's a solenoid? that moves up and down a plastic piece, So I assume that's what you're talking about, it was kind stuck, so I moved the piston up and down about 10 times to get it freely moving. If that solenoid is burned out and not moving that would be the issue? So to fix it would be replace the solenoid? Because I tried it again and still drops #6 coin into the hopper. so closed or open if I wire tie it? I guess I should say extended or collapsed position is where it should be?
