pkofman Posted October 10, 2019 Report Posted October 10, 2019 The little clock thingy in my Bravo is not good I find it very hard to read , and really tough at night Has anyone ever had problems and if so did you replace it with something else Thoughts... Peter Quote
carusoam Posted October 10, 2019 Report Posted October 10, 2019 Do you have the LCD one from the early 90s? Expect to search the latest clock threads... select a favorite clock... some have USB sockets, others have CO monitors... The latest has a back-up AI and faulty AOA sensorless system... yes... all in a clock. expect your instrument guy to have to cut a new round hole to match... PP thoughts only Best regards, -a- Quote
Davidv Posted October 10, 2019 Report Posted October 10, 2019 If you're referring to the little digital clock on the upper left part of the panel, yes I do have some experience. It was made by Mid-continent but the clock is no longer manufactured. However, it is the exact same clock as the porsche 944 digital clock which can be found on ebay. That's what I put in and it works fine. Let me know if you have any questions. 3 Quote
pkofman Posted October 10, 2019 Author Report Posted October 10, 2019 @Davidv yes top left. ( sort of a bad design in my opinion ). Hard to read.. can you remember if yours was backlit and readable at night. I can hardly read it at all. Peter Quote
carusoam Posted October 10, 2019 Report Posted October 10, 2019 Mine was lit for night use... check the bulb... The black LCD is tough to read under any condition... The closer to the roof your eyes are... the more ridiculous the LCD clock becomes... The space behind the panel, that far left... make sure your new clock isn’t unusually long... there are a few inches back there... PP thoughts only... Best regards, -a- Quote

The only benefit to the porsche replacement is that you don't have to do any panel work (that is, if your current clock is broken). If you don't mind cutting the panel you can of course source any other clock. 1 Quote
larryb Posted October 11, 2019 Report Posted October 11, 2019 I use the UTC display in GP. The clock in the panel is just there to make it legal. Quote
donkaye Posted October 11, 2019 Report Posted October 11, 2019 The clock is a bit of a PIA. The clock works great if the bulb isn't burnt out. If you can't read it, the bulb it probably burnt out. Before we learned how to change the bulb simply, we had to take the whole glare shield out and that took a couple of hours. On the second time, we found that you could just unscrew the ASI, push it down, and reach in and change the bulb. It took about 15 minutes. This assumes you have the legacy six pack instruments.The bulb can be replaced with an Audi #431-919-040 that can be purchased at your friendly Audi Dealer. I do have a complete clock that came out of my plane when I did my upgrade, but the easiest thing is just go to the Audi Dealer and get a new bulb. 6 Quote
MB65E Posted October 11, 2019 Report Posted October 11, 2019 AutohauzAZ, Pelican parts, or any other place that sells Porsche or Audi parts. Same trick in the 944. I always thought the Bravo clock looked like my 944’s. -Matt Quote
pkofman Posted October 11, 2019 Author Report Posted October 11, 2019 Bravos are great planes, ...... little tiny unreadable clock.... not so much...! 1 Quote
StevenL757 Posted October 12, 2019 Report Posted October 12, 2019 Replace it with an MD93 from MidContinent. With a couple of 3A USB chargers, it’s well worth the $465. Quote
GeeBee Posted October 12, 2019 Report Posted October 12, 2019 I will second StevenL757. The MD93 is the bomb. Nice big white LED display. Simple to operate and USB ports in the bargain. My previous airplane had one and I don’t have room in the G1000 panel now but I am looking for a way because I like it even over the G1000 internal unit which is a PIA to use. Quote
larryb Posted October 18, 2019 Report Posted October 18, 2019 My Encore has this same clock. Before this thread, I thought that it was just dim and hard to read. It has been that way since I purchased the plane, I didn't know any better, I had never seen how the clock was supposed to look. Today the clock has a new bulb and is much more readable. Another win for Mooneyspace. Larry 1 Quote
larryb Posted November 23, 2019 Report Posted November 23, 2019 So changing that little bulb is difficult, in my panel at least. There is access to the rear but getting close is the problem. I made this little tool in my 3D printer. I’ve attached the stl file if anybody has a printer and wants to make it. https://www.dropbox.com/s/4a4yxv65ahc1a5s/clock_tool.stl?dl=0 1 Quote
Gagarin Posted November 23, 2019 Report Posted November 23, 2019 What's wrong with your pilot big wrist watch? I had this Citizen for 15 years and never needed to replace the battery. A very good watch. Quote

Guest Posted November 24, 2019 Report Posted November 24, 2019 So we order the Audi bulb that Don suggested, it is a 12 volt bulb as was the one we removed from Peter’s Bravo, this made some sense as it’s supposed to be an automotive clock. Turned on the power and it immediately blew. We pulled it out and soldered a 24 volt bulb into the bulb holder, on battery and ground power the bulb was fine, started the engine, turned on the alternators and the bulb blew. Any thoughts on this? Clarence Quote
carusoam Posted November 24, 2019 Report Posted November 24, 2019 A 24V bulb in a 24V circuit... should work for years... There is no wrong way to wire it... (is there?) Additional homework... what is the actual voltage being delivered To the bulb socket? Expect that the bulb was at fault... ? Check to make sure something isn’t bleeding a high voltage into the system accidentally... that would get more expensive than the lost bulb... Check the specs of the bulb... is it really a 24V bulb? PP thoughts only, not a mechanic... Best regards, -a- Quote
larryb Posted November 24, 2019 Report Posted November 24, 2019 It is a 12 volt bulb with an inline 150 ohm resistor to drop 24v to 12v. This is in the aircraft wiring diagram. 2 Quote
carusoam Posted November 25, 2019 Report Posted November 25, 2019 Seeing if @M20Doc is around... Did you see the in line resistor, that Larry mentioned above? Best regards, -a- Quote

pkofman Posted December 1, 2019 Author Report Posted December 1, 2019 So there you have it, after a few challenges @M20Doc was able to get the little light fixed . Super happy I can now actually read the gizmo. I dont think it has ever worked properly since I bought the plane. Thank you Clarence Quote
carusoam Posted December 1, 2019 Report Posted December 1, 2019 +1 for gravity and Clarence! -a- Quote
pkofman Posted December 22, 2019 Author Report Posted December 22, 2019 Thank you for correcting the orientation of the picture. I really need to stop taking pictures while In a turn. !! @carusoam 1 Quote
