Hold on, try testing it like this:Ok IM GETTING CONTINUITY FROM ALL 5 wires on PCB . What next?
There’s the 3 thicker wires Green yellow and blue in the motor end that run through the same cable . I’ve found their contacts at controller end I’ll try to make a contact at motor end and test but I think they’re unlikely cos they’re thicker sturdier and if the thin PCB wires survived in sure they will have too
Put your black probe on one of the 6 pads on the pcb (H, 5v,GND, A, B, C.), then put your red probe on each of the 8 or 9 pins at the other end of the cable to determine how many beep. repeat for the other 5 positions. If more than one beeps for any one pad, you're out.
Basically, it's impossible to do any damage to the hall sensors or the resistors/capacitors without the cable being damaged. If your motor was OK before the incident and didn't work afterwards, conductors in that cable must have touched. there's no other way to get a problem.
