  • Not releasing Pin 8

    Last one guys i promise you.. well for now anyway

    we have a lane the also wont release pin 8 from its pin cup.. we have checked the wires, pin cup, table height everything and we are getting well and truely stuck!

    any ideas will be great

    thanks again again

    bad solenoid? maybe a pinch wire(check resistance)? pin holder?


    • #3
      we have put new pin cups on and made sure that the wires are ok but i will double check

        9times out of 10 it's the table cable. U can't go off just testing it because it might work in the position your testing it
        Keep an eye on it see if it does it again

          Again, switch consolidated I/O board to see if the problem follows the board.
          If it does, change the TIP 120 for that particular solenoid.
          The triacs for the Consolidated Electronics I/O are

          Q3:Pin 2 solenoid
          Q4:Pin 3 solenoid
          Q14: Spotting tong solenoid
          All of them are protected by CB2.

          Q5:Pin 4 solenoid
          Q6:Pin 5 solenoid
          Q7:Pin 6 solenoid
          Q15: Sweep release solenoid
          All protected by CB3

          Q8:Pin 7 solenoid
          Q9:Pin 8 solenoid
          Q10:Pin 9 solenoid
          Q16: Stroke limiter solenoid
          All of them are protected by CB4

          Q11:Pin 10 solenoid
          Q12:Ball door solenoid
          Q17:Shark solenoid
          All of them are protected by CB5

          All motor contactors,pin light relay,masking lamp relays are controlled by U1
          (ULN 2803,This is 8 darlington transistors packed in a 18 pin DIP chip),protected by CB1.

          Those transistors are TIP120's which are available at Radio Shack. Be very careful.
          It's easy to booger up the board trying to un-solder those and get them off.
          Make sure you use caution and precision instruments.
