[KikeLlano]

Hi I just need some help with my KT controller, I got 2 of them and in both cases I blowed the mosfet. I did everything like tutorials said but they still no working with something in common ones it’s connected to power supply throttle and display and I push the power button the big resistor start getting pretty hot attached picture! Any ideas??

From the pics you are using the wrong scale for mosfet testing, one should be using the DC 20 or 200ohms selector.
As the probes are covering the meter's dial one can't see what the dial is set at, but is isn't the 20 or 200ohms setting.

One should see an ohms value and not a voltage value, for the Black/Low side one is looking for three results all approx. the same value usually about 9.7 - 10 ohms but this value can be a little lower or higher. For the high side /Red wire test the value needs to be anything except 0.
