The game occasionally tilts when the right slingshot kicks, but switch test shows nothing wrong.

Road Kings tilts randomly when the right slingshot fires

Cause: The right slingshot switch was barely touching the Y-ramp through switch, only with the playfield down and in play.

Checks

• Watch for the fault during real play with the playfield down; it may not reproduce in switch test.

Fix

• Re-gap the slingshot switch so it cannot touch the neighbouring ramp switch.
