Language: Java
Controller: Black Jaguar (PWM) 2012 KOP model.
DriveTrain: Direct Drive
Any Ideas?

What do you mean by Direct Drive; motor directly connected to the wheel?
Did you notice it going into the Current Fault mode (Blinking amber-red with at couple second cutout) when you were driving around?
Please post more details like what motor you were using, gear ratios, etc.
Carefully unscrew the case and open up the Jaguar and look for any more visible damage. Pop out the PCB gently. The fan cable is connected via a connector and you risk breaking the fan if you aren't careful.
You may also want to take a look at the
Jaguar FAQ. It lists some common symptoms and what their common issue/fix is. I'm not saying that the FAQ has your exact failure mode, but you may recognize some symptoms and that can help pinpoint the cause.
