  • Table not starting on first ball

    Hi all, I have one lane that has a growing stiuation. After first ball is thrown the sweep lowers and after the time delay is finished you can hear the chassis clicking (attempting to start the table) and the tabble waits for up to a minute before feeling for pins.

    We have really old relay "B" chassis but the problem is not there. I am thinking that maybe the GP switch, I think the problem is there for some reason. Another thing that seems strange it will not set a strike 90% of the time. All of the respot cells are hooked up to their wires and the connection is made.

    Any ideas?

    <font size="2" face="Verdana, Helvetica, sans-serif">Table not feeling for pins: Jump the GP circuit in the wireway and see if the problem disappears. If it does, re-hook it back the right way and start tracing from that point all the way to the microswitch.

    Not detecting strike: Check to ensure that none of the adjustment screws are maxed out causing contact (and ground) to respot yoke, indicating a pin in cell. If all that checks out, check the cable harness itself for any exposed wires shorting to ground.

      Your chassis won't start the time delay until after it has determined that the respot cells are open. Was your chassis "clicking", the table solinoid energizing? If so, then the G.P. switch is already out of the picture. Maybe the upper contacts are just plain wore out and aren't making sufficient enough contact to allow current to flow to the motor. But that can't be because you said it isn't in the chassis-so you must have already tried a different one- I hope. How 'bout pins and sockets in the C1 plug? Loose screws on the table motor capacitors or the Caps themselves? Or maybe Mars is just way too close. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img] Bill

        Check your table cable connector plug,might be loose( over by the 4 pin cell). "Pins &amp; sockets" in that plug,too. Also, follow table cable along,it may have rubbed thru somewhere,causing a bare/broken wire.

            PAT,
            have you changed the chassis! it's been a long time since I worked the B chassis [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] it could be a problem in the stepper or a bad relay [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] if I remember right those have 12-14 relays in the chassis
            have fun! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]
            if things aren't going right just use a bigger hammer! DIRT

              I would think since it's only happening on the first ball cycle it's in the GPS somewhere. Also when he mentioned no strike cycle it led me to believe that even more. I bet there's a bad spot in the table cable, bad connection in the gps and possibly a broken cell wire touching and grounding somewhere. Keep us informed as to what ya find [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                IMHO, it depends on if the clicking noise in the chassis is the contactor pulling in. If it is, I'd replace pins &amp; sockets and any bad looking wire on the C1 plug, both on the machine side and in the chassis. Might be a coincodence that it's on 1st ball. For example, I just fixed a very similar problem at a different center that I help out in. Owner tells me table doesn't move on 1st ball only and it is intermittent. So I go there and continuous cycle it. Turns out it happened to me after about 15 mins but i go look and it's in ball 2 with the contactor pulled in. If not, I agree to look at the table cable plug and check the GS switch and wires out.

                  As farley said, if you hear a clicking noise, then it is not likely to be in the table cells' connections (cos they don't click). What might click is the contactor -...

                  But what chassis is this (in fact, I dont remember reading a machine number either in the post - but I may have lazily skipped that bit - sorry.) If it's a 70, what's the chassis setup?

                  I find interesting the comment about the table "sounding like it wants to go" but waiting for a minute before going. Where is the audible suggestion coming from (e.g. contactor, or other, etc), and what actually happens after minute - does the whole thing just "click in" so to speak - and work?

                  (sorry to ask so many questions ;-)

                  Cheers,
                  Andrew.
