Hirose HIF3 connector details all seem available, for the record: HIF3-2022SC terminals HIF3-20CV backshell HIF3BA-20D-2.54C

Always difficult to capture all eventualities, so manufacturers always add caveats. Also difficult to ascertain failure modes without access to the HW layout and SW strategies. The driver has protection so it is probably fine. If the PCB designer followed the rules then it too is probably fine (say an undersized track blowing). Let's see if the cable works on another system, though I'd advise a pin to pin check between a good and a suspect cable first to make sure there is no chance it could damage a good system. Not to say the driver isn't damaged, just saying diagnose it in order of probabilities. Just to add, I've done ISO16750-2 testing as part of my job. HTH Joe

hi all the skyscanner 2000 uses a TA7291P brushed full bridge driver, Toshiba website states it being protected. Could be a cracked solder joint on the PCB header connector (resolder them) or the little terminals could have been stressed (bent out of shape) too. Best get a correct end to end pinout table and check continuity from the PCB to the servo connections. Could also measure motor resistance and see if you get much the same at the PCB pins end with it all connected. HTH Joe
