I posted in the redemption section but I think this is the place I am supposed to post.
Picked up a Big Choice 2 button crane over the weekend... everything was functioning but the claw would not grab at the bottom of the decent. Found that the ground wire on coiled wire had frayed and detached from the solenoid. As I was stripping the tip of the black wire to resolder it back to the solenoid, the red wire popped off too. I redid the solder connections on each and I'm 99% sure I soldered red and black to the correct lugs...
Now when I power the game on the claw immediately snaps closed very fast. Everything else still works fine. The claw stays closed the whole time the game is powered on and won't open until I turn the power off. (I only leave it powered on briefly for testing as I don't want to over stress the solenoid)
The op I got it from said that I probably blew a transistor. I metered both the transistors in the claw path (per the schemetics) with red on base and black on collector / emmiter and everything checks out ok.
Is it possible that I soldered the red / black wires backwards on the solenoid? Would that cause this issue? I can say that the lug I soldered the red wire to has one little copper wire that loops down into the windings of the solenoid. It doesn't make sense that would be ground right???
Anyway I am out of options on what the next step could possibly be... Can anyone assist here?
I really need to have this thing ready for my son's birthday party in a week - so any help is greatly appreciated!!!!
This is the microprocessor board version if it makes any difference...
