I have a bally truck stop and there are 2 light that seem to be going on and off together when they should not be. Maybe someone can give me an idea of what I should be looking at. It the Y and the red diamond to the right on the pic.

Welcome to Pinside!
From the Pinwiki, it seems likely the SCR for one or both of those lamps is shorted. https://www.pinwiki.com/wiki/index.php?title=Bally_6803#Lamp_Problems

How are you with reading schematics? You'll want to check the schematic for those lamps, then test the SCRs in question.

If the table has a lamp test, run through that and determine what exactly is malfunctioning (both on every time, one comes on when the other should, etc.)

Thanks for the info it been like 15 years since working with schematics but I can figure that out.

I have all the manuals so I should be able to find it.

Thanks again
