I'm getting a chance go get back to fixing my Extra Inning machine. I have a relay that doesn't match what the schematic claims it should be. The relay is 'O' and is the Ball Return Relay. It claims to be 2B, 2B, 1C in the index, but mine appears to be 2A, 2B, 1C and the schematic shows that as well; I see 2 open, 2 closed and 1 Make/Break switch labeled as 'O'. Anyone have this around to take a look at that relay?

Thanks!
Paul

One other comment on this relay - it seems like it is permanently on, heating up and buzzing. I can share snippets from the schematic if someone has some time to help out.

Thanks in advance!

Hey thanks - here are the index listings and two snippets from the schematic. Check the highlighted sections.
Thanks!

Here's a larger view of the O and Q area of the schematic.

So when going through an EM when it isn't working right, trust the schematic over the index, or is there no hard rule for that?

Thanks for your help - I have several features I'm trying to fix on this machine right now.

The Ball Return switch is working; when the ball returns, the innings advance - but bases stay loaded. NO Ball Return switch - I'm not seeing.
DB2 is Reset Completed Relay.

Going out of town this weekend - I hope. I hope to do some additional work on this next week. Made some progress last night, then took a couple of steps back. I'll be in touch. Thanks currieddog!
