Hello,

The sequence unit in my Lido keeps resetting spontaneously during the search cycle. In the middle of a search cycle, it will reset and not register a win. This seems to only happen when the machine is closed. When I open it up and put it through a couple search cycles and watch the CU cam 16A it works absolutely fine and resets normally after stepping to the max position. I checked the CU cam 16A and it seems to be working fine (winner unit reset coil is working as it should). Originally I thought it was a mechanical problem (possibly vibrations from the pulsing sequence step up coil) I moved the sequence unit tension spring one loop around to see if that was the problem. But the random resetting is still arising. I am stumped on this issue any ideas or recommendations would be greatly appreciated.

Thanks.

Ok. I will get around do doing that. Thanks!

After putting it through a couple search cycles, you were spot on in that the search index coil is disengaging too early causing CU switch 16A to close which is resetting both the winner and sequence units.

I'm going to check the search relays later today - there doesn't seem to be a problem with the harness connecting the main cabinet to the back door. I made sure no wires were shorting together and it all looks fine. I'm also going to clean the search disc.

Thanks!

Sorry for the delay - after cleaning the search relays and search disc the problem subsided.
