Yes- 7402 only control special solenoids not standard.
Ive been back through the thread... and before we go any further i think we need to be sure that the wire that had fallen off this drop target was put in correctly.
Once this has been done and we are all sure its done right, then we need to look at the driver board cct for solenoid 4.
Skybeau's work is well known for its quality but it is possible that something happened AFTER the check.
I say .. wire first and then go from there.
Need a pic of the resoldered wire JD!
