sensor lead problem
 

i have a 120amp xcar esc and a speed passsion motor.if i use the sensor lead then it misses on 2 phases.but if i disconect the lead then it does not and runs on all 3 phases.i have tried 3 good known leads and all the same.also tried it on 3 known motors and the same thing.

There's only one suspect left, the esc.

No sense!
 

Is it possible the motor sensor board is damaged?

They are a replacement item in most motors and are liable to sensors breaking down especially after large impacts!

That's the first thing I thought. Then I read his post again, he has tried three different motor's with the same result.
