    Head lights, signals and tail lights work fine. What could be the problem?

    They just didn't quit all at once, some days they worked, others not, now, not at all.

    Any suggestions?

    I will be the first to say did you check the fuses?

    Something similar happened yrs ago....was bad ground on lic plate lights caused that, and others to go out. Think also had corroded connection inside same lights.
    Good luck

    Hey Ted:
    Didn't you have the exact issue last year?
    My fuel gauge went to empty and my right bank CEL light came on at the same time.
    Then they both corrected themselves. It must be a bad ground. You probably have a bad ground somewhere as well.
    Searching for this will be a PITA.
    Gives me something to do.

    How is NC treating you?

    I have been battling the same issue. Here is what I found--although going by memory so I could be a little bit off: All of those circuits go to a common wire at the fuse panel. They go into the lower of the two white connectors in the lower left corner, about the third bunch of wires from the passenger side. There is one large and one small wire, one or both being pink.

    I think that the wires are oversized for the pin connector so the connection is poor, leading to heat build-up and failure just like the fuel pump connection. On my car, the white connector had burned through and the insulation on the wires was a cooked mess. This is fairly simple to reach and pull out, and you can always test to see if the circuit should be getting power at the pin sticking out from the fuse board, although it is hard to reach.

    I was able to get a new white connector from Ferrari for about $8. The problem is identifying it, since they don't itemize those on the Mondial parts diagram. I had the number but it looks as if it got auto-archived. I'll keep looking, though. The local dealership figured it out by sending photos back and forth to their warehouse, so it took a few days and only worked because FoS has really good service.

    Good luck
