Me again!
I tried two different hattons 21 pin chips in three diff locos -141, 181,071 . I have a small program track set up. Wires are soldered and the connection is good. However, i cant get any reading from the chip.
Is it possible i have two dud chips? Seems unlikely, but i cant find any other probs. Locos are more or less new and clean just run in a bit on dc.
Thanks
