Over the past couple weeks I noticed that my Elektra's left slingshot was occasionally machine gunning in short bursts. Then it would quit and act more or less normal until the next time. Last night my daughter was playing and came up to tell me that it was machine gunning constantly. So I wander down to the basement to adjust the leaf switches only to find out that they're gapped adequately and the slingshot is functioning in "reverse" - that is, once it start gunning closing either switch stops it. Closing a switch again does nothing. Wiggle the slingshot arm a bit and it starts gunning again. Close a switch and it stops. Right slingshot is functioning normally. Any thoughts?

I've pulled the rubber (which was replaced no more than 6 months ago) and the behavior doesn't change. Close the contact and nothing happens. Move the arm of the slingshot or even hit the playfield with your hand and the slingshot starts gunning. Close the contact and it stops and stays stopped until you repeat the behavior.

I haven't seen a capacitor on the switch, but I'll take another look. Ditto for the leaf tensioning.

Issue resolved! Once I got into the beast and really started looking I discovered that the screw holding the slingshot coil in place had fallen out and the coil was floating around. This caused the bare wires running between the switches to almost touch. Replaced the screw - after some toothpick hole repair - and repositioned the wires. Also noticed that there's some fraying on those wires so I'll likely want to replace them at some point, but things are working now, so no real hurry. Thanks for the hints guys!
