  • Sweep won't run

    I know this has been posted before, but, I got a machine that the sweep won't run on. I found a piece of metal in the wireway. Got it out and checked the caps and wiring. Everything looked good. Put it back together and nothing. since then,

    changed chassis-no good
    changed caps-no good
    changed motor and gearbox-no good
    plugged table plug into sweep, it runs
    changed a couple of pins in c-1-no good
    I'm getting voltage at the motor plug
    I'm scratching my head here, HELP!!

    Check the low voltage switch at the control panel. Put a jumper on it or see if it is open.
    Pinspotters do not break down when they are not running!

      changed sweep reverse relay-no good

      Which switch? The sweep run or cycle?

        Instructomat.
        Either the scoring, or the managers control may have the machine in shadow bowl.
        Disconnect the wires on terminal 5 & 6 in the A&MC that go everywhere except the A&MC plug.
        Short these. If the machine cycles, there is a problem outside the A&MC.
        Hook up the 2 wires to the desk (M.C. switches) and see if it cycles.
        If it is AMF scoring, the LIU lane 'A' board could be bad - try swapping the boards.
        In the machine (back end control box), the sweep reverse switch could be bad as well as the sweep control switch. You can jump the sweep control switch to see if it is bad.

          No the motor is humming and then it trips the klixon. Only with the sweep plug hooked up. If I plug the table plug into it it works. We have Qubica scoring and XOP conversion.

            Well If the motor is humming it could be a bad cent mech swtich, but when you plug the table motor plug in there it works. That tells us the sweep motor/gearbox is good. You siad you changed caps and pins in the c1 plug. Next place to look is the sweep motor plug. Take it apart and made sure you dont have any bad connections there.

              Start Capacitor in the wireway. that is why it runs with the table plug. It is now using the table caps.

                  Re: Sweep won't run

                  I agree with Wang - it looks like you've eliminated almost everything except the sweep motor cable.

                  One other thing may be the sweep reverse switch as Ted suggested. A quick check would be simply to try running the motor backwards using the sweep reverse switch, since often they fail on one side of the switch only, not both.

                  Cheers,
                  Andrew.

                        Hmm, found a piece of metal in the wireway huh? The chances are that it has shorted something out. About the only thing left that nobody has suggested yet is the resistors that sit right near the caps under the wireway.

                        Have a good look at them and use a multimeter to compare them with the table motor resistors. Change them if something doesn't look right.

                          Good call Ray.

                          Also check that the two green resistors aren't touching each other. This can cause problems too.
                          If the problem isnt in the plug either then my guess its going to be outside the machine, as Ted suggested.

                            did he visually check the caps

                            or did he metre them with a suitable multimetre

                            i still reckon its a cap

                            has he tried taking his table motor off and plugging it into the sweep???
                            i don't need mods, i am a bloody genius
