I just (mostly) finished a restoration on a Hurricane and I noticed that whenever any of the flasher circuit "strings" are energized, all of the other flasher strings are slightly energized. It's somewhat like a typical LED ghosting issue w/ playfield controlled lights, but this just doesn't seem the same. Which ever string is intended to be energized is generally brighter, but it seems current is leaking to the other strings. Here is a short video to try to show what I mean. The upper right flasher is most evident (as well as the red one on the upper left), but it seems most, if not all the other flashers will flash somewhat as the various other strings are energized.

Not sure if it matters, but the flashers in the back box do the same thing and even when the intended bulb is to flash, it's not that bright.

All flashers are LEDs, except for a couple that are the original incandescents.

Any thoughts on what could cause this?

I might rig up a test jig to separate the output from the connectors feeding the flashers to some test LEDs to eliminate anything within the playfield wiring, but wanted to poll the audience first for some thoughts. Could this be a chip that has failed?

So I pretty much gave up on figuring out this strange flasher ghosting situation. As I’m packing the game up to transfer it to its owner, I noticed a single wire on a 5 pin connector just dangling down in the hole going from the head to the cabinet. Immediately, I recognize the connector. It goes to J106. As soon as I set up the game and plug in the connector, all the ghosting issues vanished. I can’t believe I overlooked this over and over again. Glad to have it fixed and working 100% though. 063547F8-456B-4F5F-893A-4D9302D272FB (resized).jpeg
