I am about to pull my hair and could use some guidance. I have 2 GRT HX screens and trying see aileron and elevator position on the EFIS.
Problem: can?t get the change in voltage from the Ray Allen servo to register on the Efis to then show trim position.
What I have done:
1) installed two male pins in the B connector in analog 5 and 6. Position 16 and 17 on the Primary HX.
2) wired the three servo wires. Blue to ground, green/orange to efis in analog 5 or 6.
3) set analog 5 to elevator trim in general setup.
4) Turned pull up resistor ON
When I go into trim setup, it shows volts for both elevator and trim around 9.65 but rapidly fluctuates from 9.58 to 9.67 without my hitting the trim button. When I hit the trim button, nothing different happens so it is not registering a change in voltage from the servo.
I can put the green wire from servo to red on multimeter and blue to black and set to resistance. I can work the trim and see the resistance change from 2 at far left to 5 far right trim and hold its resistance number when I release trim button so the servos are sending a signal.
Can I only wire this to secondary display instead of primary? Is there something else I am missing as this is so frustrating.
Thanks
Shawn
