Jaguar repair?

Yes you can repair them depending on the severity and extent of the damage. However there are significant flaws with the gray Jags that IMO would make the effort required to repair them in vain. If your issue was with a black Jag I would suggest attempting to repair.

The gray Jags lack ESD protection, contain more FET's of higher Drain Source impedance and, if I remember correctly, significant board layout differences that effect heat dissipation. The current sense resistor is undersized and adds more series resistance to the bridge adding to the heat issue.

The black Jag contains ESD protection on all of the exposed pins, has a more robust layout, contains fewer FET's and has a high side current sense circuit that uses a 2mOhm current sense resistor of a higher watt rating. I have yet to ESD a black Jag, I have however ESD'd almost all of our gray Jags.

Even if you are able to repair your gray Jag you will most likely be repeating your efforts in the future.

Since your question was regarding repair, I will leave my interpretation of the legality for a different thread.
