OK, looking at the back of my Turn Coordinator, there is a 3 pin connector. There are 2 pins on top and 1 pin on the bottom. A is Positive, B is Aircraft Ground and C is not used. Which pin is A and B. I think A is the top right and B is top left, but I want to be sure. Thanks for the help.

HI Larry,

I too am working on my panel. I feel your pain . . .

I am not familiar with your kind of instrument, but I have an idea which might help. If you look carefully at the case around the pins in question you might find the "A" or other pin name embossed on the case.

Good luck,

Paul

Hi Larry
  I think if you check with an ohmmeter you will find the ground pin B is connected to the case. I recall having to do this to Identify.

It is a Cessna Instrument and I can find no markings at all. Just a sticker telling me what pins are positive and negative.
