Ok I have tested my resistor for this, and all these components look fine, my hand controller was not plugged in, nor was my input/output.
It's strange that fusion would have the same resistor burn up and put it down to the h/c cable, yet mine isn't plugged in and this resistor burns.
Also it worked fine before, all I did was unplug it, mount it and plug it back in. The 12v is coming from my accessories as it was before (I'm actually scared to wire it up to the ECU power now incase it causes something bad to happen). I've double checked the polarity is correct.
I'm all out of ideas - my last hope as I see it is replace all the components S-Kid has outlined in red and try again.
Does anyone have any suggestions?
