  1. Well. after getting the plane up on jacks and doing a little investigation it became clear that the gear motor was on its way out. So, the motor and the gearbox are on the way to LASAR for rebuild. Interestingly I have heard that motor failure at around 3500 hours is not unusual and my M20C has almost exactly 3500 hours on it. Guess the motor knows exactly when to quit!
  2. Thanks for the very lucid explanations. Obviously I misinterpreted the use of the term interconnect that I had seen somewhere in reference to the bladders. The fact that each tank feeds only the fuel selector makes perfect sense.
  3. My current M20C is my first Mooney with bladders. I understand there is tube which connects the left and right tanks. Now for the stupid question. Because of the tank interconnection is my assumption that both tanks are feeding the engine regardless of the fuel selector position correct?
  4. Recently had a situation where the gear retracted fine and fast (as usual) but was very slow extending and would not go all the way down. Cranked the gear down and landed at my favorite FBO where they are evaluating the issue. I suspect the motor is giving or has given up the ghost. I understand there is someone in CA who can rebuild the Dukes motors (if that turns out to actually be the problem). Does anyone know who that is and how to contact them?
  5. O.K. folks here's a poser for you. My '69 M20C has decided to start discharging the battery even with the master off. I've put a meter between the battery and the contactor and can discern no drain (not even a few ma) with the switch off. The battery (Gill) is only 6 months old but it has done this twice over the past month. Everything else works just fine. With a freshly charged battery it starts right up, the alternator keeps the battery charged but let the plane sit for 10 days in the New England cold and battery voltage drops to about 9.8 volts and that's not enough to turn over the s
  6. Interesting comments but not necessarily helpful. In this case we have a situation where the shunt is sound, the wiring to the meter is sound and regardless of what load is placed on the electrical system with the engine not running you can't get more than about a half needle negative deflection and upon startup when you should show a significant charge on the ammeter, again you maybe get half a needle positive deflection. Now admittedly it would appear that the meter is the most likely problem but again I have seen the exact same situation in two '69 Mooneys. Were the meters they used real
  7. What is it with Mooney ammeters? My first Mooney was a ‘69 M20C which was one year old when I bought it. The ammeter never really worked barely showing a reading positive or negative regardless of load. Never solved the problem in 5 years of ownership. Move forward 45 some odd years and I have another ‘69 M20C (go figure) and the ammeter barely registers. The battery stays charged and a voltmeter reads 14 volts when the alternator is operating. Ignoring the ammeter worked back in 1975 but I’m older (if not wiser) now. It seems odd that two planes separated by 45 years would manifest exa

  9. Not familiar with that schematic as it does not seem to appear in the service manual and the additional schematics I have don’t seem to reference that number. Can you provide a copy by chance or indicate where it may be found?
  10. I can highly recommend Lawrence Airmotive at LWM. While they are not a Mooney service center Nick, the owner, is both a very talented mechanic and services a number of Mooneys. Assisted by Brian And Mike you will get both outstanding service and will be dealing with friendly, highly competent and efficient technicians. I have dealt with Nick and Brian for many years and would not go anywhere else.
  11. The issue I’m facing is that the overhead, gauge and compass lights are functional but while the intensity is variable, they do not go to full brightness and the clock light and quadrant lights are dead. Looking at the controller schematic for later models it appears that there are two feeds coming from the controller. I suspect one of the transistors in my controller is shot which is impacting both problems. Thoughts.
  12. Not so much an answer to the problem but a request from another ‘69 owner with a panel,light controller issue. Does a schematic exist for the control box? The service manual is worthless as regards this issue essentially ignoring any real reference to the control unit.
