Slingshots work a few times, then score but no longer kick until the game is powered off and on.
Slingshots stop kicking after several fast hits
Cause: Not a fault: System 3 slings are CPU driven and the software disables a slingshot that fires many times in a short time, to stop a stuck or close switch machine-gunning the coil.
Checks
- If slings cut out in normal play, check the sling switch gap and that the rubber isn't holding it closed.
Fix
- Nothing to fix if it only happens during rapid hand testing.
- Re-gap any sling switch set too close.
