I'd not thought of that possibility
The thick wires to the battery are widely separated as it is a cuboid SLA,
so plenty of run to put a current probe around at that point. At the moment
I'm struggling to get the tubular framework back together. I assume when
they assemble it, it is done under force so each corner joint keeps
everything else in place, the screws must be for show or they do not hold it
all together as far as i can see. It is made to be foldable like a folding
bike and triangular sections and one triangle locked and braced against
another

If there is a next time I'd reverse the jaws of a sash cramp to force the
tubes apart, the 2 inches or so to release the cross tie tube. I wonder if
the chassis of those disability/mobility scooters are built the same way.

Now road tested I see how the traction works. Gearbox will spin backwards
because of course pitch and angle of the worm / spur gears, I hope there is
protection against the reverse emf generated as off on the control is not
fully off, 5volt measured just by leasurely hand spinning.. Then presumably
"spring" clutches in the wheels one L and opposite sense in the R one to
again allow for total freewheeling in one sense and somewhat braked in the
other direction.
