Posting a query often results in a solution being found,
even before any responses !
I had tried a new battery,
and I had grounded the other pin(s) with no discernible improvement.
However, the track power was supplied by 11.1v Li-Po,
and replacing this with a conventional 12v supply, resulted in perfect running.
The puzzle was that if battery power was low (which I didn't unfortunately check)
why it did not affect running in both directions, or give an indication.
Possibly because the resistance goes from 0-10K,
and not from mid-point to 0 and 10K ?
I would appreciate any info re the LED,
to save the controller being left switched on.
