Me again I've got a pm42 when I short out sections one/two and three it does what it's supposed to do ie if I short out any one of the three the other 3 keep working but when I short out number four the unit shuts down I've looked on line but can't fined any thing can someone help please.

I've tried another pm42 and it works so it's not my wiring . Wondering if it's a reverse loop set up !

Puzzling. Not quite sure what a one of them is but if one is a reverser and the others are not then it could well be the culprit.

I never did get a reverser myself even though I wanted one, but these days I have abandoned DCC as I missed DC too much. (Not sure why. I just did!)

Someone will have the answer.

What is a PM42 and what is it supposed to do? I am familiar with most Lenz, but the only Digitrax items that I bought were two loco decoders as back in those days they were the only loco decoders that one could limit the top speed. Jolly expensive things costing the same as a loco each!

Surely if a different one is OK the other one is faulty.

Yes it looks that way I have not done any program changes so that's that then.

Digitrax offer a one year replacement called No Worries. If its older than a 12 months they also offer a repair service. I'm not sure who is their UK repair serving agent? But it must be worth seeking out a paid for repair as the worse option should be cheaper than a new unit (Though the PM42 has been superseded now by their PM74 unit)

Good luck
