This is on Wms Heat Wave 1964.
The drop target value increases with gameplay. The two outlanes score the drop target value when lit.
The drop target stopped scoring when dropped and here's the weird part-- the outlanes, when lit, would score late. Instead of scoring as soon as the ball hits the rollover, it wouldn't score until the ball was well past the rollover.
Cleaning the contacts on the drop target switches and the drop target relay seems to have fixed it (for now, anyway), but why would the scoring be delayed? Seems like it would either score or not. Seems very weird to me. Any ideas?
