Ok, thank you all for your anserws, I think cut off contactors should be a standard couse in some cases like overload, shortcircuit, fets sticiking, diodes shorts --- >higway controller should react ultra fast, ideal software could check throtle position and current as well for 0 throtle PWM=0 if not true contactor off...
...anyway I am happy what I have and I have decided to put few thermostats 60 degree C opened on mosfets conected in series on contactor line and driving with laptop to see what temeprature I can have on heatsink maybe it is easiest way to read current, temperature etc.?
I hope so I will not kill any one on road if some above cases will occur to me, lucky I have clutch.
