Thunder,
In exactly what way did it overheat? Was it smoking, just hot to the touch, or did it tell you so via CAN bus? It is not likely to get hot under normal conditions. However, if you say that the motor it was feeding was also hot and so to the wires it is connected to, then yes it could get how. That is an indication that you are running near max currents on the motors your are using. Max current on the CIM is 129 amps which over a length of time will heat all components in the electrical system feeding that motor. The power FETS used in both the Victors and the Jags are rated for 40+amps each and there are three FETs wired in parallel which should handle the loads we have.
If the Jaguar was smoking, it is likely damaged. If it reported over temp on the CAN bus but was not hot to the touch, you may have an error elsewhere.
