I have recently installed a D-180 and cant seem to get my MP indication to function properly. On initial power up, the needle will slowly climb to 20.5 and stabilize after about 30 seconds. Based on my field elevation, I should see 27. It does not respond at all to vaccum or pressure. I have tried 3 sensors, two of which are brand new, and even unplugged the sensor completely with the same 20.5 reading. I have verified 5 volts and ground at the appropriate pins on the sensor connector, though the ground is showing 2 ohms through the 180 to airframe ground.
Tonight I will ring out the remaining signal pin to the d-180 connector.
Assuming this pin is correct, I'm out of ideas. What else should I be looking for?
