    A little different oil temp behavior - temp drops, then returns

    It does, but it only suggests it’s not the D180 sensor ground. All the other sensors are grounded to a common sensor ground (fuel pressure) or a sensor housing ground (oil pressure) and the oil pressure housing ground ties back to the firewall. The oil temperature ground is the only one...

    A little different oil temp behavior - temp drops, then returns

    Air guy, typically most people see a rise in temp with grounding issues, it’s all over the forum, here and VAF. This seems unique in that the oil temp goes down, and all other sensors - fuel pressure, oil pressure, stay rock solid. That alone points to sensor or single wire issue. I do have the...

    A little different oil temp behavior - temp drops, then returns

    D180. Single wire oil temperature sensor. 117 hours on a RV-9A. Normal oil temps during flight of about 180F (deemed plausible in previous experimentation/oil cooler testing). During today’s 1.6hr flight, the oil temp would periodically drop to 120F-ish, then return to the 180F range. A...

    EMS setting for D180 fixed Sensenich 2600 rpm

    Thank you for making the effort to clarify this.  I'm still struggling a little to understand.  I was able to do some 8000' DA flying yesterday.  After weeks of bad waether here, it was good to get off the planet. Anyway, with the redline set for 2600 in compliance with the sensenich operating...

    EMS setting for D180 fixed Sensenich 2600 rpm

    Thank you for the reply.  Setting yellow/red is what I had read earlier as a key element.  Since what I think is happening is the % power is reading higher than actual by 10%-15%, what is your best guess about how far and in what direction to move the adjustment factor?  I’m really not worried...

    EMS setting for D180 fixed Sensenich 2600 rpm

    A/C is an RV-9A with a O-320,  Sensenich fixed prop limited to 2600 RPM and a D180. For best % power accuracy, what should the recommended green to yellow and yellow to red setting for tach be? This is not equipped fuel flow, so it sees MAP, altitude and altimeter, and Tach. Forgraphical...

    D180 ASI error troubleshooting

    Thanks. I'm looking for (hoping for) the big chunks at the moment with 8kts off. 1. Understood on a 4 way being sketchy, but it's fast. Once I get looking for less than 5kts, I'll be flying a triangle as described. Honestly, I don't know how much the two methods would differ in this case, as...

    D180 ASI error troubleshooting

    My RV-9A has about 3 hours on it now, and consistently shows an 8 Kt difference between the D-180 ASI and GPS four-ways. The ALT is within about 20' through most of the range, suggesting it's not a static issue. Static and pitot were leak checked by the avionics shop without the pitot mast in...

    loss of EDC10 communication

    Ok, I'm back at this. I have updated to 5.4, no change in EDC 10 behaviour - it's fine at power up, but sometime between 10 minutes and an hour, the D180 flags the 'lost esternal compass" (paraphrased). Pins look good - I used a good crimper. I revised the shield grounding (now grouned only...

    loss of EDC10 communication

    The issue grows more interesting.  The EDC10A comes back with extended off time.  The EDC then drops out with extended (30 min or greater) on time.  I don't think this is wiring. Power, gross wiring inspection all ok.   Read thread, checked pins . . . The only issue I can find is I grounded...

    loss of EDC10 communication

    System is D180, AP74, one SV32 on the DSAB. RV-9A in my garage.  Everything communicating 100% up until Saturday, when 'beep beep'  - enough to make me look up.  EDC10A comm error, loss of compass, loss of oat.  Powering off the D180 did not resolve.  DSAB is up and running fine (not expecting...

    D180 slow to boot?

    My D180 has been rock solid up until today. Today I hooked up a fixed 13.8v lab power supply (rated to 9a cont., 12a 5sec) to my main bus (still under construction RV9A) and fired up the panel. This is not the same p/s I have used previously. Regardless, the D180 takes minutes (3-4 -5) to go...

    D180 to G496 connection

    Thanks. That worked. Rick

    D180 to G496 connection

    The setup is a D180, AP74, G496, SL-40 and GTX327. It's been a frustrating day trying to connect my D180 to a G496(and SL40 and ELT). I've used the EFIS D-25 harness pin #22 (serial RX) to the blue output pin on the G496. GPS is set for Aviation In/NMEA & VHF Out at 9600 baud. I've tried...

    Serial Altitude info to Garmin GTX-327

    Thanks. I'm bringing all my instrument grounds to the same place(common rail) so no issue - we'll see if that works for the 496 to SL40 rs232 link. :) Rick
