Hi folks.
During a flight yesterday, I noticed that FF indication on the AFS 4500 intermittenly where reading 0. Since it was not dashes but 0, I assume that it was the red cube who where sending a false signal to the 4500.
The engine was running normal the whole time, with normal EGT and CHT indications.
Reason for the assumption is that I think I remember from the install, that when the 4500 does not receive any signal, the corresponding line reads dashes.
During the rest of the flight (15 mins in a straight line back to my home field), the FF intermittenly showed normal indications, but mostly 0. Never any dashes.
This weekend I'll check all connections and lines to see if I can find anything wrong. If not, I guess a new red cube is the only way to go.
The engine, a stock Lyc IO-360, the the 4500 and the red cube was installed in 2012, first flight 2014, and TT is now 240 hrs.
Has anyone experienced a red cube indication failure after 240 hrs? Or is it something else going on here?
