Hi, I have a Chicago coin Red Baron. Last problem to fix is the game over lights. Game plays fine and ends at the proper time, but the game over lights behind the backglass will not light. I looked at the game over relay and that is fine. Any other ideas where I can look? Bulbs are good so. Thank for the ideas!!!

Inspect and diagnose this circuit with Alligator clip jumper wires

For a switch to work 3 things are necessary:
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening

Test the socket itself by jumping it to a known good one.

Thanks guys for the ideas. I especially appreciate the jumper idea. I always worry about jumping things, because I don’t want to mess things up more.

The problem is fixed and I will document how I tracked it down for future reference.

I jumped from a working light to the non working light. It worked. So I jumped from the game over same colored wire to the non working light and that worked also, so something between the game over relay and the light was causing it not to work. I went to the connectors between the body and head. Found the same colored wire in the bundle and found a loose connection in the connector.

Thanks again for the help. Brian.

Well done BBC !! I couldn't have said it better.
