Sorry for slow reply Nigel, I've been away from the fun stuff. I use a digital multimeter set to 20vdc to measure what i hope to be 12v. Battery is a bit flat though so I'll try again later when I've found a replacement. John

Thanks Nigel and Andrew. Encouraged by your replies, I persevered and added some weight to the stripped down chassis plus a dose of switch cleaner to track, wheels and wheel contacts and bingo the loco grunted when I attempted write a minor change to the decoder. No more "no loco found on track" messages. Does this problem mean that the package data is sent at a voltage much lower than the 14.5V supplied?

I'm new to DCC and have for the first time connected up a new SprogII to a test track and to my lap top running the latest DecoderPro. I have installed a new Lais 860021 in an old loco. Both Sprog lights are on steady when powered up. Putting the loco on the track changed nothing. Pressing the identify tab in DecoderPro input page set Sprog flashing but no volts measured on the track or at the Sprog output. The DCC Address field was populated with a 3 at an early stage before I checked for volts. Does that indicate the decoder was working at that point? I have checked the decoder wiring against the Lais manual several times and it seems OK. Can anyone suggest what is causing this? Is this a Sprog or decoder fault or something else?
