Bally Night Rider em. When you rollover 100k, the buzzer stays on. Quite annoying.
New! Dark mode!

If the delay is controlled by a blinker bulb, then it might have shorted out or someone didn’t install a 455. Just a guess.
As noted above, the Delay relay uses a 455 flasher bulb, which might be burnt. It is right there by the relay so it will be easy to find.
Bulb stays on. I removed it and buzzer does not activate at all, which is preferable to being stuck on. Are there different 455 bulbs? I tried a few I have on hand and no change. Bulb stays lit for good.
I’d plug that bulb into a playfield or backbox socket and see if it ever blinks. Seems odd to have a bunch that don’t blink. I have found some that blink on or off at weird rates so that they don’t look good in the back box and then I swap them out. Sometime old ones are better, other times I prefer brand new ones.
The delay circuit is counting on the current draw to be low enough that the light stays on so you hear the buzzer, but not forever, so that when the bulb heats up and blinks, it lets the relay drop.
there is a #55 lamp that has the same bulbous glass design but doesn't flash with a standard filament.
the #455 lamp has a bi-metal filiment inside.
I think you can see the difference in this pic.
When I picked up an Aladdin’s Castle it had a 55 bulb in more or less the same circuit. I had a spare 455 but it wasn’t flashing. Bought some new ones from pbresource and the first one worked as it should and the buzzer only stayed on as long as the bulb stayed lit (about a second or so). Good luck!
I put in an old 455 bulb I had and it works correctly now; buzzed for about 3 seconds and stops. I guess the batch of new 455’s I have don’t cut it for this application. Thanks everybody!
