Dassault F900 Fueling FULL Light ON

Original Issue:
FULL fueling light on Refueling Panel (24QS) G3 is illuminated although fuel tank verified not FULL thus preventing any fuel being applied to the right hand tank.
Later issue:
The G3 FULL light starts to extinguish “most of the time” therefore allowing fuel to be applied to the G3 group.
Comments:
Video shows testing of system. Thermistors for FULL shut off were verified to not be of any issue. Wiring from L12QS/R12QS to 9QS verified to be good.
Throughout the video there are different combinations of tests with 32QS removed, 9QS swapped out with 12EK and 2EK along with tests of the fuel shutoff valves via “TEST” push button on 24QS.
One major thing to note is the inconsistency of the RH G3 tank FULL light compared to the G1 & G2 tanks which seem to always operate the same.
The video is long because it requires so many tries at different combinations and each provides different results as the testing continues. When you suspect that 32QS is at fault, later on you’re led to believe that 24QS may be an issue followed by the potential that 9QS is the culprit.
