You'd be wrong. They trip for anywhere from a fraction of a second to a second or two. Self-resetting.

A multimeter was applied to the Jaguar input power while it was run off the ground no major issues were noted (but multimeters are fairly slow to measure).

Nyet. Measure voltage drop along the wire - from power board to input screw, and output screw to motor connector - while passing high current. Only way to spot a bad wire (in this case) is under load. An Ohmmeter will steer you wrong.

When they are 'locked up' there's no current draw, you won't see anything of interest - too late in the process.
I think 1676 will be visiting 11 soon, we'll look at the practice bot with you then.
Back to basics. Maybe build a test platform without external influences - just the bare basics - and see if you can reproduce it on the bench. Time-consuming, yes, but ultimately can be valuable. And it'll keep the students involved.
