Potentiometers

[Doug94]

1. I have two Ray Allen trim servos (roll and pitch) and a Lycoming 4 cyl Fuel Injected engine. I'm unclear on the White/Green wires - do they both get wired into one wire (#4 which is labeled Elevator position potentiometer) or does the roll trim servo get wired into a different wire which I am unclear on and need some help?

2. Where does the #1 wire - Battery voltage get wired into?

3. I also have a Garmin 430W wired into an ARINC and Skyview system. I've gone through the configurations and still get a message in the Garmin 430W message screen that says "no 429 signal on Channel 1." Has anyone experienced this and do you have the fix?

Thanks

Doug

Here is the connection for the Ray Allen servo.

Thanks for the schematic. My servos are hooked up to the coolie hat switch and the trim relay board what I cant figure out is the hookup to the Skyview. I guesse I need to ask does the skyview have trim indicators? I thought it does and the potentiometer leads from the EMS hook up to the white/green wires of the Ray Allen servos. That then takes me back to the original question - Does the #4 wire labeled elevator potentiometer get attached to the elevator (pitch) trim and what does the roll trim get hooked up to? Thanks

1)No. Each of the signal wires goes into their own GP input that supports trim (Any of the A/B/C types of GP inputs. See the installation manual for details. . Basically, SkyView comes setup with only elevator trim setup as an example. You add roll trim by mapping the pin of your choice to the roll trim function. You then connect the roll trim's white/green wire to that pin, and elevator trim to pin 4 (if you haven't changed from the default pin mapping). You'll need to make adjustments in the EMS SETUP > SENSOR INPUT MAPPING, and then go through the other steps to calibrate each trim axis as documented.

2) Any voltage you want to measure (battery, ship's power, etc). It's a voltmeter, basically. It's not a power source, to be clear.
