RJR posted:Do not confuse voltage reading on the TIU, which should be reasonably accurate, with variable channel voltage reading on the remote, which is only accurate (sort of) when the input voltage is 22 volts.
Do note that the Track Voltage reading on the remote softkey is read by the board in the loco, which is downstream from the rollers and the fine wiring in the loco. Between that sensor circuit and the voltmeter in the Z4000, there is also the track, the leads, and the TIU, all of which tend to reduce voltage.
Thank you! This is in regards to the fixed voltage output - I am not using variable outputs - I think the variable output was only referenced because of Barry’s information in his book - and we haven’t found info regarding this particular issue.
I am just surprised there is that much of a drop in voltage from the voltage reading in the engine as compared to the actual voltage of the track.
Thanks again for your help! Your info about the voltage of track to the inside of the engine makes sense.
