First, we discovered that the motors leak power into the water on all leads. Maybe some level is okay but we think that our readings were too high.

James happened to have a perfect water test tank. It was a 5 gallon bucket from a project that had holes cut in the side. These holes allowed us to bring the ROV connector outside of the bucket for poking and prodding.

In any case it needs to come all the way apart and fortunately there is a small loop of extra wire for the entire harness. That will give us some slack to try fixing the seals on the motor solder joins. All nine motor wires need to be repaired, we think. The only external wires that passed the continuity test go into the IMU, indicating maybe the motors are the problem and not the SHH joints.
