1991 300zx NA speedometer strange issue

Hi, the car speedo rise up proprtional in time with the car not driving! So just the needle goes up until maximum in cca 15 min. It rise up slowly, permanent.
i try to disconect the speed sensor but nothing change.
the wiring seems to be ok. Put out the instrument cluster and clean the 4 rusty bolt that fix the speedo.
take a look at the spedo itself and all soldering seems Ok, very clean inside
so something get same voltage with time.
Any ideas or who repair this items?
i try search on internet different source but seem an atipical problem.
thanks, kristian
