  • Pindication problems

    Hi guys,
    I have just taken over at another center, and my dilema is my last 6 lanes are MP chassis to which i have NEVER set eyes on before, what my prob is that 2 of my lanes have no pindication the machines function fine just no 1st or 2nd ball lights etc.
    I assumed that like a SS chassis there is a Klixon that functions in that circuit and i noticed that the MP chassis has 2 of them, BTW both of which metered out just fine, i noticed that connected to of the overloads was a what appeared to be a rectifier so i changed that and now have 2nd ball light just no first ball, what is strange is that the lower LED's on the masking unit card do not light up even on 2nd ball but if you run another chassis they do????
    So what guys, controls pindication in the MP chassis, just to rule out already i tried the MP board from the next good working lane and no difference,
    ANy help would be greatly appreciated fellas..

    Cheers Brett

    Check to make sure there is a ground on the mask socket pin #33. I had a chassis a loooong time ago that didn't have this wire and you don't get a 1st ball light. Should be a wire going to a ground in that pin.

    I've had enough of hope & chains.

      I don't have MPs but we have two styles of LED mask cards, with different pinouts. So, just be aware that that may confuse issues.

      And I agree with Jon in that with these mask cards, a missing ground can give misleading behaviour (some lights working anod not others).

      In most of these cards, the 1st ball is always on thanks to the ground wire Jon mentioned. However, the oher style of LED card we have doesn't have an extra ground but an extra 12V connection. They were for 30 machines previously.

      So I suggest comparing carefully a few of the chassis, plugs and mask cards to note any differences.
