 =====Solution=====
-/31/2021. Replace the Sensor Wire with a new one.  Across the middle pins on the Sensor Wire should have almost zero resistance.  Test all spare wires.  Have three good ones remaining, 6 broken wires.  All wires in King Probe Box.  Will order thermo compound for King Probe Box to use on heaters.
+/31/2021. Replace the Sensor Wire with a new one.  Across the middle pin (of the 5 pins) on the Sensor Wire should have almost zero resistance (conduction test, not open circuit).  Tested all spare wires.  Have three good wires remaining, 6 broken wires. All wires are stored in the King Probe Box.  Will order thermal compound for King Probe Box to use on heaters, which we should store in the King Probe Box.
+=====Problem=====
+High Slave Voltage (01/14/2022 - David Delene). During the January 14, 2022 IMPACTS flight, the King Probe Slave voltage was above 6.0 volts all during the flight, when the voltage should be 5.0 volts.
+=====Solution=====
+/14/2022. The slave negative connected on the analog to digital board was not secure on the screw connections. Put new pin ends on all slave and signal, positive and negative connectors.  Installed the wires to the screw connectors making sure the wires don't move.
+=====Problem=====
+High Slave Voltages (01/17/2022 - Jennifer Moore). During the January 17, 2022 IMPACTS flight, the King Prove Slave voltage started with 5.21 volts before take off. After take off, and during the rest of flight the Slave voltage was between 6.1V to 6.2V, which is above the usual 5.0 Volts. Additionally, the LWC value for the King was steady during flight at -0.4 g/m^3.
+=====Solution=====
+/18/2022. The slave negative and signal negative was labeled incorrectly for the analog to digital board wiring.
+  * Blue and White wire - Slave high
+  * Orange and White wire - Slave low
+  * Black and White wire - Ground (Disconnected)
+  * All White wire - Signal high
+  * Green and White wire - Signal low
+=====Problem=====
+Low Slave Voltages (11/11/2022 - Jennifer Moore). After installing King probe on hot-wire boom during NASA IMPACTS integration, noticed that the M300 was not receiving data from the King. Before probe installation on 11/08/2022, the harness was tested for 28VDC. Additional wire testing was done after noticing no data on M300. All wires going from wing to rack pin out properly, and all wires going from wing to probe pin out properly. A test was done on the sensor wire showing that the slave pins and master pins were all good- the hot-wire sensor does not need to be replaced. It is good to note that during a wire test from the 'king meter to A/D board' wire and the harness coming from wing to king meter box there was only two of the four pins completing the circuit (SL- and Sig-).
