I've just finished restoring a Dr. Dude and ran into a small issue. I replaced the slingshot switches on each one with new ones, and wired them exactly as they were before. I double checked and no wires are inadvertently touching anything they are not supposed to.

Yet when I hit the left slingshot, the left flasher (Magnetic Personality) fires, and when I hit the right slingshot, the Drop Target flasher on the right fires. This occurs whether they are LED flashers or incandescent. Of note, the flashers fire regardless of whether the coil fires when the slings are triggered so I don't believe it to be coil related.

I've attached pics of the switch wiring. There was already a diode on one of the two sling switches (the one with 3 lugs) for each slingshot and I carried these over from the old ones. I'd be surprised if both went bad and that's the cause. I think these are 1N4001 diodes which I have on hand but not sure if new ones would fix the issue.

Any ideas?

This is likely a switch matrix issue. Diode shorted/open, diode installed backwards, switch wired incorrectly.

They are wired correctly, the diodes maybe bad. Do a switch test and see if multiple switches fire at the same time.

Are you sure they aren't supposed to fire? I think that might be part of the game.

I'm pretty sure when the slings fire on mine I get a flasher firing on that side as well.

Well you guys are right. Every gameplay video of Dude has the flashers firing with the slings. I cannot believe I never noticed this. Insane. Problem solved!
