  • Strike cycle 1st ball cycle

    Ok, 82-70 machines with Omega-tek MK70 boards... one lane has a *WEIRD* problem with sticking between cycles. After a strike is thrown SOMETIMES it will go through the normal strike cycle, but will not spot pins, instead, the masking unit just starts showing the first ball light ON (while strike light is still on). this is not chassis related, but may be something strange that the chassis doesnt understand.... really weird, sometimes it wont do it for a month, other times it will do it 7 times in ONE LEAGUE! Any ideas?

    Re: Strike cycle 1st ball cycle

    If the machine goes to first ball after a strike cycle, then you can rule out a ground problem in the fingers.
    I would firstly look at the spot relay to be faulty, in the chassis. Or the spot solonoid itself not engauging, so the table would only run down to re-spot position and the shuttle would also not be activated.
    Also check the table cam microswitches. TA2 in particular. Ensure switch isn't sticking, and also ensure that cam is correctly adjusted. If TA2 is out of adjustment, then the sweep will run to 270 degrees, and NOT stop at second gaurd, carring on back to zero.

      could be the spot relay socket as well. Try gently twisting the relay in the socket to see if you either get spot back or loose it. If it changes when doing this, just replace the socket.

        Sorry I wasnt very clear, it was late at night when I posted. The table DOES NOT move... the machine looks exactly like its waiting for a 9 pin, but never moves even if there is a 9 pin in the bin because the chassis switches over to first ball cycle (while still showing strike on the chassis, so you look at the mask and it shows the first ball AND strike lights on). Its a VERY strange thing... we've tried different chassis on there, and the same thing happens.

          If TBL cam adj doesn't fix it try changing the 9 bin microswitch. Just a guess.
