FERRARI 360 All dash lights on to nothing

I Have a 2000 360 with f1 transmission and have been having the problem for about a month now. When i go in to start the car sometimes it starts up and the dash lights up every single possible light and hazards come on also and gauges work as they should. Other times I start it and nothing lights up not even the needles car will still drive and go into gear but zero lights on dash. I have checked battery, alternator and alternator power wire. all Ok. has 14000km on it, any suggestions? thanks.

 

YES only light that works on the cluster is the airbag light
