Thanks Frank.

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.


Geoff
