I use the search before but found no solution.

The Spartan2 is connected with black wire (electronic ground) to Aux input O and green wire (linear 0-5V)  to signal.

Spartan2 is powered with a 12V batterie.

When I power Spartan2 the other AUX inputs get unstable and to high in values.

Is there something to ground?

Hi, black and green should be correct. Can you measure at the connector when you connect it to YourDyno and when not? Could it be some issue with two different ground potentials?

When nor conected toYourDyno there is only 0.3mV but it looks that there is some potential. When messure ist show 300mV but drop down to 0.3mV

Is YourDyno conected Voltage between 0V and Signal is 2.15V and same time oilpressure and temperatur jump up to the value they have at 2.15V

The Spartan2 was defect from the beginning.
