Jaguar repair?

Has anyone attempted to repair a damaged Jaguar?

I have two malfunctioning units. Both will emit smoke when driving the motors forward.

Opening them up reveals that one or more FETs (I am presuming they are FETs) show signs of heat damage - the plastic around them is melted, the grounding tab is discolored. Also, the central cap in one unit is bulging slightly.

A multimeter test indicates low resistance between V- and M+ on both units. I think this is consistent with the observed behavior (i.e. smoke) when driving the motors forward.

My plan is to simply replace the damaged FETs and the central cap in one of the units.

Has anyone done this before? Does anyone have any suggestions/comments?

Thanks,
ER
