Vesc over_temp_fet

after a few months of waiting i finally got the board back from school. hooked it all up and im getting the same issue. the temps on all MOSFETs and PCB are 400oC. i changed the battery cut off and start to what you recommended and nothing changed??

Take a pic of your vesc, your temp sensor maybe damaged

Which is the temp sensor ?

R1 is the temp sensor

R1 is here.

So if the vesc fets are reading 370 degrees will it be this resistor? I removed mine and it reads 6500ohms which seemed in range to me. 6500 ohms - approx 35 degrees celcius. It’s horrible in my shed in summer.

@Jebe - Yeah, correct. 20-30 Celsius is about average.

So R1 looks ok - what else can cause this??? BTW - extended caliber hanger please !

Ah got it - Had the wrong HW version checked when i uploaded the firmware. Maybe this answer will be helpful to someone else
