I adjusted the drop targets today on Abra Cadabra, just moving the mounts (occasional hangup) and for one game it was great. Since then though, i originally had the issue that 500 points (drop target value) was continually registering from the moment the ball was placed in the shooter lane. Assumed I had a drop target switch stuck, looked, no problems. Dropped the play field back down. 500 points no longer registers on the ball being placed into the shooter lane, but now roll-overs and drops don't register score. they register hits.
I don't have a schematic on hand to trace this through, but i am suspecting something may be incorrect with the Q relay as from memory its common between the drops and rollover registers for points.
All sling and pop bumper scoring is correct and registering.
Machine correctly re-zeros on new ball
