  2. I have a 78J and in need of some covers. How do I know if they are Kilxon or ETA? Also, do you sell all the caps or only specific ones?
  3. Still available?
  4. Yes, possibly interested. Can you advise on price?
  5. Do you have one to sell? Thanks,
  6. I am looking for a used standalone fuel flow (or possibly combined CHT/EGT/fuel flow) indicator. Preferably 2". I have the transducer and relevant lines...just need an indicator that has some approval on Mooney.
  7. Potentially interested in the JPI...how much are you asking and can you send me your number to discuss?
  8. Is anyone aware of an STC that approves the Davtron 550 (? I think) fuel flow indicator in the Mooney aircraft? The 1978 J model we purchased had one installed and trying to find the approval source.
  9. thanks all. Used the QD cleaner and did the procedure, recalibrated per the mm. didnt seem to fix it unfortunately.
  10. We cleaned and recalibrated the unit per the other thread to where the light comes on at 12.5 (per the service manual). It still seems to come on in the low 13s or high 12s...initially shows up as a dull glow. Anyone have access to a schematic for the IAI unit?
  11. What type of electronics cleaner...the spray on screen cleaner or something else? For cailbrating the pot on the bench, you apply regulated power to which pin then watch for the flashing? Manual implies to do it on the aircraft while running and doesn't clarify either.
  12. Have a 78 M20J. We are seeing intermittent issues where the low voltage annunciator light flashes. I don't have a full time voltage display, but I have checked it with a digital readout in the cig lighter as well as a page on one of the avionics. It seems to be consistently fluctuating between 14 and maybe 12.8 or 12.9. All should be above the low voltage threshold. Alternator appears to be supplying power (if I pull the field breaker the ammeter goes negative right away). Battery has been replaced with no real change in behavior. Alternator is relatively new. Seems to be loosely tied to load, as it's more likely to occur with a lot of stuff on (landing light, etc.), but it doesn't directly tie to loading (can also occur with minimal load). I suppose voltage regulator could be suspect, but I'm struggling to tie all the evidence together with a failure there. Any thoughts? Thanks.
  13. Good to know. I have a step and one piece belly for what its worth. Interested in the old vs new door assessment.
  14. Thanks guys. I'm really surprised to hear that. It seems like I'm at least 10 knots below book. Regarding the inner gear doors...anyway have a good estimate on what those add? The speed is better on the later (flat?) inner doors as opposed to the clamshell? Anyone know the part number or reference on where to get? I think I see that Mooney Mart has those?
  15. Have a relatively new to me M20J. Engine is strong with high 70s compression, and prop was just overhauled. Extensive annual where gear doors / cowl flaps were rigged, and all flight control rigging was checked. The inner gear doors were not installed when we bought the plane (and the fairing that go in front under the wing are missing as well). As part o the annual we peformed the SB (forget the number) which removes the ram air (since it doesn't really really do anything on the Js). The brake calipers are installed in front of the axle...not sure if that is an STC or something else. Question is this...not seeing near the speeds expected. I haven't done a true 4 way TAS test yet, but at 9500' (10 deg C) flat out (21ish inches MAP, 2600+ RPM, 10.2 GPH, one on board, 3/4 fuel) I was seeing around 152ish knots. Book says we should be around 15 knots higher in that configuration. Other than the inner gear doors which I understand adds about 5ish knots (?), anyone have any suggestions on what may be happenning and why the numbers are so far off?
