the braking resistor wasn't located on the switch board and may be located in the grip. as far as opening the grip to see the motor, etc. i didn't do that. they may even have a blocking diode there, but i didn't look for that. to be honest, i would think that systema may use another fet to switch in a braking resistor and it may be located either in the grip or on the fire selector circuit board. to access that board would require a teardown of the lower receiver that was beyond the scope of this repair. perhaps there is an issue there that systema has resolved when they update the PTW with a new electronics version, and i may yet see it.
