  • Cycle Soleniod Running Hot

    Just lost 2 cycle soleniods (240V A2 Jap)in about as many days

    First one died (soleniod buckled inside) found black and burnt relay contacts in time delay module my assumption is that the contacts fused together. Changed TDM & solenoid... still runs a little warmer than I would expect

    Second one has been having trouble for a while (fail to cycle) thought I had it. Come in today and once again plunger stuck in soleniod... [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]

    Any ideas would be appreciated

    Check your reset wiring. You may have a short somewhere energizing the solenoid. I've had that problem before. Happy Hunting! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

      I agree with Brandon on it is a reset wiring problem.
      Check all the reset wires running up the underlane track towards the power lift paying close attention as they go down the accelerator.
      Also check your reset button on the ball rack up front.
      It can stick and cause the solenoid to stay energized too long.

        I don't know much about JAP machines but when this happened to my machines what happened was there was a microswitch that kicked off the soleniod after it energized. In other words when the soleniod tripped, it needed something to de-energize it. If the soleniod didn't shut down, it would melt the inside of those plastic soleniods.

          Is there a chance you might be installing a 110
          volt solenoid? I had that once & after a while
          the plunger stuck in solenoid.
          I would think if you had a pinch in reset wiring
          running front to back, it would be obvious, with
          recycles & set ups. If you are having numerous
          set ups you might try unplugging reset line from
          electric box and politely ask your lg. bowlers
          to throw an extra ball in the tenth frame to clear
          off pins.
          One other thing I just thought of, I had Bowl tronics electronic triggering in the centers and
          if there was something wrong it could cause constant firing.
          Good luck

          retired and still guessing

            Thanks to all for your help all solenoids that died were rated at 208/230V, no respots/recycles, Thinking of reset switches, electronic triggering and reset buttons just thought about some thing else auto score relays 10th frame relays...

            First machine: has had 2 or 3 CB trip outs since changing TDM and solenoid?? not thinking straight enough tonight to chase this one...

            As for my thoughts on the relay contacts in TDM after removing relay from TDM was obviously cactus put new one in and no problem with TDM (on another lane)

            Second machine: fixed loose mechs reset switch and found that if you rotate the black button on the end that screws into the reset switch you can actually jam the reset switch closed??? and put new soleniod in no probs so far

            Thanks again to all
