Gauge Problems Ground OK but nothing works !!??

[Rosart]

Problem is on a 944 Turbo 220 1987.

The indicator of the headlamps and the red light under the voltage are OK but... nothing else :

No indicator for turning light
No speedometer
No RPM
No voltage
No Oil pressure
.......

The Grounds of the 3 connectors in the VDO gauges are OK.
The gauges are OK (I've checked with gauges from another working dashboard).
Fuses are (of course) OK.

Any idea ????
The neiman ??


Thanks in advance
