I took apart my space station to clean the playfield off and wax it. When I put everything back together, the turning space station diverter stopped lining up properly. This uses two opto switches to position but I can't figure out what is wrong seeing as I didn't touch the motor at all. Any help would be greatly appreciated.

Also, I tried cleaning them last night to hopefully try to get it to work but to no avail.

Tried that but it didn't work. When I put the whole machine together there was a ahort between two circuits. What did they have in common? The Space Station board. I found one bad transistor and one of the switching diodes is letting current through both ways.

ok...well that wasn't all the problem. The one switch is still causing a short when it is triggered. I will take a look tomorrow night at it to check it out.

Is anybody here familiar with opto switches? I checked the circuit board and I didn't find any shorts at all. Could the opto switch be bad? How (if) can you test them to see if they are the problem. The problem I have only occurs when the second opto switch is triggered.

I can't test the opto to my knowledge unless the game is on. Currently, I have the playfield on my dining room table and I am going to check all the circuits and replace any necessary wires. There is too much butchered wiring on here (wrong colors) that I just need to check it all out. I think it will save time in the long run.
