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

Its on order. Things don't appear overnight in Australia from the US.

Advancing the score relays in the head manually works correctly.
Have noticed that the 500 point relay g locks on. All the playfield and drop target switches for it don’t seem stuck closed though

Advance bonus relay locks on also after rollovers have been triggers.So confused

The 500 point relay does nothing when hitting a 500 point target and the ball trough won’t register end of ball reliably.

10s hundreds and thousands work fine by themselves

Trough registers fine if the drops or rollovers aren't triggered. So strange. only doesn't end the ball if you've clicked one over.
The switch is clean and gapped correctly. It registers 95% of the time, only time it doesn't register is when a rollover , usually the 3, has been triggered before.
