If the output of the decoder is producing 15 v dc power (i can measure it with dc meter) as the dc engine is running at full speed does that tell us anything about the decoder. ?If i did short the output and damaged it would it still produce the dc power.?
Using jmri to read or write to the decoder doesnt seam to work. It cant determine what decoder it is. Entering the type manually and trying to read or write cv¡¯s give errors and each cv takes a very long time before the error is indicated, usually a no acknowledgement error.
I tried to use the throttle to program a 2 digit address. I entered address 10.
When ?i place the dc engine on the test track ?being feed by the tcs m1 decoder output wires and feed by the track outputs from a dcs100 command station and turn on power with a throttle the engine runs at full speed. ?When i turn the speed knob whose address is set to any arbitrary address nothing changes.
When i set the knob to address 10 and turn the speed up the command station power to the track goes off and its beeping. If i turn the knob speed back to zero the track power comes back on.
Does this tell us anything about whats wrong with the decoder and what its damage is.
I am sure i must of done something to short the output but what or Howe is not clear

AD,
Yes. If the decoder gets damaged with no LOSADA on it then thats how it got damaged as the dc loco on the track when i first tuned on the power had issues not to mention if the wheels were dirty or track was dirty.
Running a decoder with no load on the motor outputs will not damage a decoder, but you cannot read CVs.
However, in your case any short on the DC test track connected to the motor outputs would damage the decoder.
That¡¯s why i am trying to establish if the decoder can handle an open ckt on its output.
A decoder can handle an open circuit?on its output.
A decoder?will quite likely be damaged?by a short of either of its output wires to any other connection (including the other motor terminal).
