  1. "Almost no mice were harmed in the production of this lubricant"
  2. Yes, I agree that sometimes chasing ghosts can cost a lot of money. When you look at the technology involved in our sensors and probes it's relatively basic so it's understandable that there may be some variation. For instance, I thought I was having an oil temp problem and the vernatherm was to blame. Prior to doing any expensive investigation we cleaned all of the contact points on the oil temp probe and sure enough the temp went back to where it was prior to my "issue". I spent a lot of money chasing what I still believe to be an EGT "ghost" earlier this year when it was really my fuel totalizer that was giving me a higher than actual fuel flow.
  3. I always thought my bravo was very loud but it turns out it’s not that bad compared to others at about 90db in cruise at 29/2400 at 9.5k yesterday. I’m going to see if there is any difference when I’m up around 20k tomorrow. In any case, wouldn’t want to do it without the A20s or something similar.
  4. I'll add another item from experience. Make sure that the turbo transition exhaust piece is in very good condition. This is the the T junction that collects the exhaust and sends it into the turbo. it's a cast piece and none of the welding shops (Knisley, ect...) will repair it. If you see heavy discoloration or pitting, a replacement may be in your future. The cost for the unit and slip joint are $6K.
  5. Of the many things to look at, check the logbooks see if anyone has done any maintenance on the speedbrakes. With the lack of flying you may be looking at a $2k overhaul. Ask me how I know. Also be mindful of when the last prop overhaul was, those are more seals that like to dry out over time with little use.
  6. Thanks, if I can’t solve it at first I may ask a friend who also has a bravo if I can put my repaired regulator in his plane to see if everything works the same. We will have to get out the wiring diagram as you suggest.
  7. Yes, it blew on the ground right after I hooked up the repaired alternator. As I mentioned, the shop that repaired it checked it twice on their equipment and they claim it works fine. I’m not sure about disconnecting the wires but I’ll troubleshoot that on Monday when I go back to the MSC that installed the alternator. Thanks for your help.
  8. I’m hoping the collective wisdom of this forum can help me solve what has become an annoying issue. A few months ago I was mid flight and I received a solid LEFT ALT indication on the annunciator panel and the left alt field breaker popped. I continued on the right alternator and then had the problem diagnosed by my mechanic in FL. They used a volt meter and determined the issue was in the left alternator with possible arching. I ordered a replacement alternator and had it installed a few days ago. After installation the left field was not receiving any power. We swapped the voltage regulator left and right plugs and sure enough the right was no dead and the left now had current. The annunciator panel was now showing a flashing red indication for the left. We then determined that the voltage regulator needed to be repaired. I went to a very reputable shop in Islip called Consolidated Aircraft Supply (at the recommendation of @kortopates and I was extremely impressed with their setup. They had a test box that was built specifically for my regulator. They found that a transistor in the left side was bad and had it replaced. It was bench tested and worked perfectly in the shop. When I reinstalled the regulator in the plane the left side was still not functioning and the left alt field breaker popped as soon as I turned on the left rocker switch. I brought it back to the shop and they retested the regulator to find that it was still working perfectly on both sides. After many hours (and a lot of $), the issue is still not solved. Has anyone seen this before or have any ideas?
  9. It must work differently in Texas than Florida. They don’t collect any driver license information in FL. I’m sure if they put in some effort they could identify you but they really only have your name and unverified address in FL. When you get to the testing site you just hold your license up in the window of the car and they pretty much just see if your name matches.
  10. Ok, as others have mentioned there is a possibility everything is fine with the engine but just know you’ll most likely find things in the first year of ownership and flying that will red to be replaced such as seals and other items that benefit from regular use...
  11. A lot depends on where the plane has been sitting. Dry or wet and salty climate?
  12. Yes, agreed. I now realize that my response may have come across the wrong way. I certainly did not mean everyone should get tested. I only meant if you want or need to get tested Walgreens is a good way to go since the amount of information you need to provide them is minimal.
  13. If it’s available in your state I recommend the Walgreens drive through test to everyone. They don’t collect any information besides your name, address, birthdate (no social or any other personal info), it’s free, and I’ve gotten results in less than 3 hours.
  14. Thanks @kortopates!
  15. It looks like a need a new voltage regulator for my Bravo. Dave at Modworks was more than helpful in putting in my new left alternator today but it looks like the left side of my regulator is bad. As many of you know, this is a very expensive and not very available part since it’s a Mooney part number and not a third party. Has anyone gone through this and had any creative solutions?
