I have a problem with my new v3.1.
The power button is not working. As soon as I plug it in the fan comes on and I have steering and power with a solid red led lit. When I press the power button to turn it off the led goes out, fan is still on still have steering but no power. When I hold break for 5 seconds to power it off I lose power but bot steering and the led goes to a solid green.

Any help greatly appreciated.

On a side note the esc is a week old and this is my first race weekend.

Have you tried unhooking sensor wire or motor wires? (Make sure motor wires don't touch each other while unhooked)
