  1. Thanks Pritch. Were your other panel gauges also fluctuating? Do you know of any way to identify if the alternator clutch is the culprit?
  2. Thanks for the LOC on the resister, should be easy to check it with a meter. The fuel pump is STRONG so I don't think that is the issue/
  3. So sorry to hear this. My condolences.
  4. Today going into PWA, I started to get a rapid flickering of the Volts high/low Annunciation. It was not the steady flash that you see with a low voltage indication, but a flicker. I pulled the field breaker for the alternator and the flicker was replaced with the steady flash for low voltage. This was about 10-15 min before touchdown. Once on the ground, at 1000 RPM the power fluctuations got so bad that the radios and GNS530w were going haywire. I immediately shut off the avionics switch. Now, rewind a bit. Ever since I purchased this aircraft the ammeter has been bouncy. It is positive but fluctuates. I was told that this was typical. I dont like it though. I can even hear fluctuations in the headset associated with this movement of the ammeter. Today after flying in another Mooney almost exactly like mine I noticed immediately that the Ammeter in it was rock steady in the positive. I cant help but feel that this is how it SHOULD be. Back to PWA.... So I was a bit freaked out that the alternator had failed and my batteries were dead as I was getting the low voltage flash when on batt only. I made a call and got someone to come take a look and help me out as I had 0 means to troubleshoot myself. They were able to help me determine that the batteries were charged AND that they were getting the proper voltage with the engine running. I went to an auto parts store and got some contact cleaner. I removed the master switch from the panel, wires still attached (soldered to it) and disassembled and cleaned that janky little switch real good. This solved the low voltage flash on just battery power, but did NOT solve the jumpy ammeter issue OR the flickering of the low voltage Annunciation. Also, i noticed that the other panel guages were also slightly fluctuating. I do not know what do do next. Does anyone have any idea what is going on ? How can it be normal to have a fluctuating ammeter, but in another Mooney exactly like mine the thing is rock solid at all RPM? I would really appreciate any help on this! I want my ammeter to be rock steady!
  5. Sounds fun but the rules prohibit anyone with a turbo from participating.
  6. Hey everyone. My low boost is not functioning. High boost works just fine. As I understand it the only difference is a resister in the circuit for the low boost. So I suspect it has gone bad. Where is this located? Or could it be something else ? Thanks!
  7. This stuck out to me too... I happen to have had a close encounter in an aerostar. I was out flying with my stepfather at KDTO. I was flying under a hood and he was vectoring me around doing practice IFR approaches. We had done a bunch of them and it was starting to get dark. I see the factory fuel gauges are getting pretty low. My stepfather was watching the totalizer. We did a touch N go and I noticed that this 700 superstar was more of a rocketship than I had ever seen... I said, hey, lets Land, the fuel is looking low and she is flying LIGHT. My stepfather was convinced we still had plenty of gas from looking at the totalizer. But he relented and we landed. Told them to fill the thing as we were leaving. We got a call the next day from a friend who worked at Daltons. He was like " uhh, we put in 162 gallons, how much does that hold again ? " I was NOT very happy with my stepfather that day. IIRC the aerostar holds 164 gallons. Also, the two engines are both fed from a fuse tank, so you dont get the luxury of having one flame out b4 the other like you might in an airplane with 2 separate tanks feeding each engine.
  8. I just dont believe this is an issue for the batteries I am talking about... here is a link to battery car for Shoria batteries. https://shoraipower.com/dl-377291/TopTipsSheet-032015.pdf They say as long as you are using the battery in a vehicle that has no draw when not in use, you will only need to use the special charger once per year. They also give advice for starting in sub freezing weather. They can be stored for VERY long periods of time. Here is a link to one that is 34 amp hr with 540 cranking amps https://shoraipower.com/lfx36l3-bs12-p130 it weighs like 6 lbs! You could have 2 of these in parallel and have 1100 cranking amps with 68 amp hours... for 12 lbs... what do concord batteries weigh? Here is a blurb on the chemistry A lithium-iron battery is also a rechargeable type of battery but made with lithium iron phosphate (LiFePO4) as the cathode material. While lithium-iron is a newer version in the lithium battery family, its anodes are also made up of carbon in batteries. Phosphate based technology possesses superior thermal and chemical stability which provides better safety characteristics than those of Lithium-ion technology made with other cathode materials. Lithium phosphate cells are incombustible in the event of mishandling during charge or discharge, they are more stable under overcharge or short circuit conditions and they can withstand high temperatures without decomposing. When abuse does occur, the phosphate based cathode material will not burn and is not prone to thermal runaway. Phosphate chemistry also offers a longer cycle life. Lithium Iron Phosphate (LiFePO4 ) characteristics: Most stable Good density Long life Economical Maybe I need to think about getting an STC to put them in various aircraft. Could do the industry a ton of good
  9. I am not quite sure that smaller versions such as for RC helis are a fair comparison for the larger versions for vehicles.
  10. Do you have any experience with LiFe batteries ? I do as I use one in my glider. I never said they had better energy density than other lithium batteries... only than Lead acid. They can be stored for YEARS if put in the store voltage range. Yes, there is a special charger for them that will slow charge them. However I charge mine regularly with a normal car battery charger as allowed by the manual. There are lots of motorcycles running around with them.
  11. Hah, not exactly. My partner and I are based at 2 different airports and we each pay for hangar. So you can imagine we run into situations where one of us has to go without. We like the idea of having 2 aircraft to share so that if one is down for maintenance/improvements or annual we still have one available. We have not decided for sure if we are going to spring for another. We wont pay any more for hangar, but fixed annual inspection cost and insurance will go up. We are still mulling it over.
  12. Corn Flake.... I did not say LIthium ION.... I said Lithium IRON / LI FE... this is completely different that Lithium ion. There IS NO thermal runaway.. in fact Lithium Iron (FE) is the MOST stable battery technology we have. It is VERY light It requires NO sophisticated management (although for extended none use it is preferable to connect them to a charger designed for them ) They are high capacity and high current, especially considering their weight ( on par with lithium ion)
  13. You may be right, but it begs the questions: Why wouldnt they explain that to me? If I already had a G3 system, would they sell me a new display if mine broke and was out of warranty? If I bought the entire kit, is there anything that requires me to install every feature?
