Elektrik: Tankanzeige

[Beumers]

Hi all

I've got this fuel gauge that is not working. When I turn the ignitionkey the orange low fuel level light works in check control mode. In the self diagnostic sequense everything works also the fuel gauge.
I checked the contacts on the fueltank with a multimeter and the measurements seem close enough to be right. The fact that I get a reading from the mm is reason enough to believe that the sensor in the tank is in working condition. The signal does not reach the gauge in the dash, At least that is my conclusion.
2 questions.
1 Could a defective capasitor on the electrical print in the instument cluster be the cause of this problem. I read that there are 5 of them and they seem to be the cause of a array of problems.
2 Does anybody has a diagram of the pins of the plugs that go in the back of the instument cluster, so I can see what pins are responsible for the fuel gauge. I've got the model with the blue backcover. I think it's a '92 model.
You don't have to reply in English. I fluently speak and read German but I stink in writing. Takes me to mutch time.

thanks again for the help last summer. My climate control is working like new again.
