On the Swinging Target, are you sure it’s not being pushed back enough to lodge under the playfield plastic, therefore causing the switch to get stuck?

On my Space Mission, if you hit it just right with a strong flipper shot it used to periodically get wedged until I finally bent the plastic down just slightly with a heat gun.

If both kickers are stuck adding points it’s likely not the switches underneath. Hopefully some of the experts on here will weigh in.

I had an issue with my Gottlieb Jumping Jack where the ball would land in one of the two kickout holes at the top and keep adding points but not kick the ball out. Thanks to HowardR and his help, it turned out it was a switch on the Score Motor that was not closing. You might have a switch in that circuit somewhere that is gapped too close.

If no one else weighs in I’ll look at my schematic when I get home from work to see if I can locate possible causes.

I’m thinking now that both kickout switches might be wired together but I can’t remember for sure. If so a switch gapped too close on either kickout might explain that part. Do they both fire at the same time?

Hard to believe I can’t remember, having played my Space Mission a ton lately.

Just checked the Space Mission and the switches for the kickout holes at the bottom are wired together and both kick when one is activated unlike my Jumping Jack.

I’d start there. Hopefully one of them is gapped too close.
