    Switch table and sweep relay already?
    The impossible often has a kind of integrity to it which the merely improbable lacks.

      Sounds like you might have a bad connection in your SP relay socket. It is pretty common for the terminals to get burnt especially #6 and #7.

      You can replace the whole socket or there are some empty terminal pins that you could remove and change out with #6 and #7 with. To remove them just straiten them out and push thru. The ones with wires attached will have to have all of the soldier removed off them first before pushing thru. I would recommend putting the burnt terminals back in the unused spots because it helps hold the relay tight.

        Does the spot solenoid engage at all (you'll hear it buzzing)?

        Have you tried changing the spot relay?

        Should inspect the C1 pins as well.
