Brief Description: Complete GP sensor Wiring, Bleed Brakes
|
|
1930 - 2200
Today I corrected the GP input wiring by removing the pull up resistors on GP 1, GP 2, and GP 5.
These GPs, as previously discussed, are used for the elevator trim, aileron trim, and flap position.
The crosstie discrete was moved to GP 4.
While this sounds easy, the pull up resistors were wired in close to the gEA24 connector and were difficult to access. The resistor pack was removed and the remaining wires were capped and tied off.
The GP 4 discrete still required the resistor, so a single 5k resistor was spliced in the middle of a piece of wire which was then connected between pin 50 and pin 15. all joints were soldered and protected with double wall heat shrink.
The GEA connector was reconnected and the wires were organized and tie wrapped.
The MFD screen was then reinstalled and the system powered. The configuration was updated for the Crosstie change, and was operationally checked.
Next, I worked on bleeding the brakes, again. Hopefully, the fitting will not leak this time.
