TCU Switch.

by Josh Esser in 912 / 914 Technical Questions 6 years ago

Hey everyone. Just wiring up my plane. I have a used 914 and it was set up on the Isolating switch to just break the connection on wire 14. In the manual it shows breaking the connection to both wire 14 and 2. Do both connections need to be broken? To me it makes sense that it would be ok if only one was.

Thoughts?

To maximize safety, it is important to use a DPST switch to isolate both terminals of the servo motor! (Should the servo motor ever happen to have a short circuit condition, an SPST switch could potentially not properly isolate it from the TCU module.)
