Troubleshooting advice for panel mount GPS installation (UPDATE - Solved!)
Hi All,
I finished wiring in my King KLN89B GPS and Dynon D10A/EMS-10 over the last couple of days, and both are working great with one exception - the GPS resolver interface.
The GPS thinks the CDI (KI 209A) is always at 15 degrees +/- a degree. Calibrating the unit doesn't help; it just stays at whatever value the calibration value sets it to. I've triple checked the wiring and it matches the King-supplied diagrams. Everything else works correctly; the self-test moves the needle and to/from flag as would be expected.
Can anyone offer any suggestions on where to look next? My guess is that perhaps one of the units are bad but I'd still suspect a wiring issue before a bad unit. The interface is quite simple - only four signals - and as I mentioned I've verified correct continuity several times.
Thanks for any advice anyone might be able to offer!
