  1. 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
  2. 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

  4. 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?
  5. 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.
  6. 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.
  7. 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.
