Thank you sir.  Can you check the lower right side of your monitor and see if there is a green light?

Oh yes sir.  If the lights and power is out in your building, your computer will not work.

I think you need to figure out if it’s the accutrack that is dead or something else like you are not getting a signal from the nav source or your servo control valve is bad. You can check the accutrack on a bench top fairly easy. Connect it to a 12volt source and put a 100 ohm resistor across the leads going to the servo control valve. You can at least now check for some voltages. Even easier find someone near you that has a working accutrack installed and swap boxes. If you want to fly to Jax Florida or meet somewhere we can try that.

Hi @Hector thanks for your generous offer.   I'm taking the ship back to my installer tomorrow so he can spend some more time troubleshooting.   The maintenance manual that I received from Cecilia, formerly of Brittain Ind., has a lot of great troubleshooting advice in it that my installer can try to test both the accutrak and the valve.   I'll keep your offer in my back pocket in case he can't solve the problem.   A flight to JAX would be fun.

The lights behind the rocker switches are on.  That is all that works from the pilot's perspective.   I'm going to let my installer figure this one out.

One of the better threads for troubleshooting.

Update.  My installer found the issue with the Accutrak II install - the unit had a bad connector.  He replaced it and the system is working great.  I flew 74 nm back from his shop today with the Accutrak II slaved to the Garmin 430W, and my track on flightaware is a straight line.   I'm really pleased with it.  Cool to see 1960's discrete electronics still working as designed, and getting along with our "space age" tech.
