Default Sensor Hall Testing and Replacement

Does anyone have any experience testing and/or replacing the sensor halls in their motors?

I had a nasty crash on the track yesterday which paralyzed my car, if you gave it a gentle push the motor would start back up, but once at a complete stop, the car was immobile again. After playing with the mechanical settings/ replacing the sensor cable with a brand new one.. the motor eventually stopped working. Then I replaced it with another known working motor and that motor started cogging severely too. So then I figured maybe it was a bad ESC. Then I replaced the ESC with a known good ESC and the cogging was persistent, now with a known good ESC and good motor that were not part of the original crash. I then placed s 3rd known good motor on the second ESC and the cogging was still there.

I am now at a loss... I seem to have introduced some sort of "Cog Cancer" and I am afraid to connect any more electronics in fear of spreading more cog cancer.

I have since ordered a sensor hall tester from RCMart and plan to verify all the sensors are bad on my now 3 non functional motors and 2 non functional ESC's.

In retrospect, if I had a sensor tester, I could've easily verified if I had a bad sensor cable or motor right off the bat before ruining my ESC and cascading my issue to other electronics

It would be benificial for you and those who might be able to help you if you provide us with the brand - model/version - wind/Kv of what motor and esc you are using.

I am not interested in starting a brand war as I've heard this sort of problem exists regardless of brand of motor used. I am more interested in learning which brands do in fact offer sensor hall replacement parts, I think that would be more beneficial information along with any pics or video demonstrating how to replace a sensor hall should one get banged up on the track.
