Temp. sensors and fan 928S4

[Marco@928S4]

Hi,
I´ve got a problem with a 88 928S4:

after changing the timing belt, both fans run countinously. I can only stop them by removing the fuses.

Is it possible that only of the temp. sensor is broken?

I can only find 2 sensors on the top of the engine and the sensor of the freon.

Whats about the electronic control unit?

Does anybody has a wiring diagram for a 88 928S4?

I need the circuits for the fan control and the wiring of the temp. sensors.


Bye, bye Marco
