Dear DCC users, I have an intermittent voltage measuring issue, not an operational issue, at least not yet! About 2/3 the time I measure half voltage and the other times full voltage. Now this occurs whether I measure across the rails or if I measure at any of the boosters from Rail A to ground plus Rail B to ground. I have the system set to about 16 volts. When measuring half voltage I get a reading like this. Across the rails= 8.00 volts Rail A to ground= 4 volts, Rail B to ground= 4 volts so the sum is 8.00 volts. I have a large S scale layout with 6 boosters and this measurement phenomina occurs at all boosters. I probably have 20 engines all with sound on the layout all the time.
So far this has caused absolutely NO operating problem. If I wasn't measuring the voltage I wouldn't even know it was happening. I discovered this while voltage matching the different boosters. I don't have any shorts, no blown decoders, (I have snubbers at the end of all main runs) The one thing I did not do was twist the wire pairs of the main runs as I was not aware of the need to do this during construction and I do have some main feeders in the 50 foot range, that's why I installed the snubbers.
I am using a Digitraxx DCS 200 with DB 200 boosters and one DB 210.
