  • puzzling problem

    lane 1 at 36 lane center does this only once in a while. call is sweep down. get there and the sweep is down with strike indicated, and no pins on the deck. hit 1st. ball 2nd. ball button and sweep raises and returns to 1st. ball. cycle machine and runs fine after. may happen 2 or 3 times a night or not at all for a week or two. really agrivating. have checked all wire ways and switches. even changed chassis. chassis omni-tek boards. any suggestions are welcome.

    Brian, need a little more info. Is sweep at 66 or 270? Are fingers open or closed? Thanks.

      Re: puzzling problem

      Lane 1 at my house was doing this every now and then too. Try swapping the bin switch. Even though it works some times, the switch could still have bad contacts. Also, is it always on a strike or does it happen on second ball as well? Double check the chassis C1 and C2A plugs for bad pins. A burnt pin could cause this problem as well. But I would start with the bin switch, that was what was causing my problem. Also, post the answers to GPS questions too. I am assuming that the sweep is at 270 because the you said the strike sign is on. But if the sweep is at 66 that's a whole different ball game.
      Give me a hammer and some duct tape and I can fix it!

        Re: puzzling problem

        I went thru the exact thing a couple months ago..
        Check the table cam switches...bad switch,bad wire or loose/bent terminal.(mine was a bent terminal...shorting out intermittently).
        I never had a "10" ;..but ,one night after closing,..I did five " 2's" !

          brian,

          i assume you do not have shortened strike cycles, turn the TA-2 screw so the cam lever moves further away from the cam (engages sooner).

            Re: puzzling problem

            My guess is;

            1) the most obvious-the bin switch

            2) Chassis plug connections

            3) TA-2 switch or adjustment

            4) off-spot switch

            Good luck

                Brian, for some reason I think your spot solonoid is not pulling in. Strike ball is thrown. The scorer recognizes this, sweeps any dead wood and the table wants to spot new wood. If yor spot solonoid does not pull in at this time the table will run to a respot height and your fingers will close just like on first ball. The machine thinks since the table ran that it spotted wood. Find out why spot sol. is not energizing and I think you have your problem solved. Good Luck.

                  Another place to check would be the spot relay inside the chassis. This little guy is responsible for energizing the spot solenoid (among other things).

                  A good way to test your spot solenoid is to make a test cord and run 120VAC directly to the solenoid (with machine off) and see if it pulls in.
                  Also make sure the solenoid is DIRECTLY over the linkage. You don't want the plunger of the solenoid to bind...will cause the problem you described.
                  If the solenoid checks out, the Spot Relay could be at fault.

                    Re: puzzling problem

                    A bad solenoid won't keep the sweep at 270 and he says its not in the chassis so its not the relay.

                      brian,

                      do this for me, and yourself...raise the mask on lane 2. clear the lane of standing pins.

                      ASSuming ss chassis. . . .cycle machine by dropping sweep to first guard using SA. after table reaches 266 and sweep runs into pit....hold TA-2 out with your finger and dont let it back in...is that the same prob you have with lane 1??

                        Hey coors, I have had the problem you are describing but the problem Brian is referring to only happens on a strike cycle. A missadjusted cam switch would happen on a normal first ball cycle also?

                          When I went thru it, the machine did the exact same thing ,ONLY on a strike cycle, & INTERMITTENTLY ( not all strike cycles screwed up) ..TA-2 switch had a bent/loose terminal.... [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

                            it sounds to me like a strike lock. the finger cells are probably closed and the sweep is at 270. I agree with the post earlier about a bad relay. we had a mechanic do teh same thing by pressing 1st ball 2nd ball button to raise the sweep then cycled it adn the table spots a full rack. however the next time u throw an X it locks up again. the way we clear it is too shut it off for 5 secs adn the table will respot the phantom rack then u just cycle it. U either need to change the chassis or change the relay.
