ALT LED blinks but will not light up when pressed

[danburdette]

Could you please elaborate on "Cause" and "Corrective Action" on this issue with altitude hold button flashing. I am still in the build phase of the RV-9. Initially when installed several months ago, the LED stayed on when engaging altitude hold and the servo became active. But now the altitude hold button flashes when engaged, servo is inactive. The ADI 1 appears to engage normally. The Altrack is pin 9 is connected to pin 7 on the ADI 1.

Hi Dan,

Pin 7 on the ADI Pilot is an auxiliary RS232 input. If you want it to be engaged with the ADI Pilot I, connect pin 9 of the Altrak to pin 16 of the ADI Pilot I. That should do the trick!

Lucas,

Good job! Pin 16 did the trick. Works as advertised now. I would probably not have resolved this problem without your tech support.

Thanks,
Dan
