sttng has additional 8-driver board that control four coils and some lights.
2 subway diverters, and 2 other coils called, "Drop ?"
None of these Four coils show signs of life during test.
Machine never go to "ready to play" and keeps doing ball search.
We did have a melted coil sleeve in One of the subway diverter coils.
Changed that coil, but something else is wrong.
No mention of what fuse does these four coils in manual! lol ??
Solenoids Coils #37, 38, 39, 40
These coild all get 50V from J107, Pin #1
We do see this pin reads much lower than pin 2 and 3 (also 50V)
This is 50V AC current that powers these coils?
Not sure what to check next?
Have no clue what fuse would be on this 50V circuit.
Why would One of the Three 50V pins not have juice?
