Hey All,

I recently moved my space station to my brother's house. It was completely working before it got there. After setting it up, it started to have several issues. I spent all day disconnecting switches and replacing diodes to no avail. Any help would be greatly appreciated!

Single drop target in test mode activates the entire first row:

Disconnected all tilts and replaced a few diodes with no change. Also, when the drop is down in attract mode, it causes the right bottom flasher and relay to work:

The S, is still causing an immediate slam tilt. We replaced the diode with no luck. I believe this is the standard slam tilt for space station, but not sure:

Hey Grump,

Jump those pins triggers the entire row. Coin slot 3, rollover 1, shuttle second t, station o, u USA, r. Lock entry, lwr rt 10, bottom bumper.

In addition anything jumpered with j8 pin 5 always triggers that whole row. Other pins jumpered with j10 pin 3 only return the one switch.

So, it’s the column. Transistor or resistor pack?

Thanks!

Thanks @grumpy!

All pins were high except J8 pin 5 was low. What does this mean? DennisT yes, I know PinWiki , but if grumpy is willing to help, I’m very grateful!!

Replaced Q43 and all is working. Thank you very much Grumpy for all of your help!!!
