I recently added 2 sidings, and they both show a reading of about 3.5 volts when I have the power toggled off for the sidings and turned on for the rest of the layout. Does this indicate I have some kind of wiring issue? My locomotives all seem to run fine.
Here is my setup:
1) I have DCS with 2 TIU's powered by 1 Lionel 180 watt brick.
2) I use 6 channels of the TIU's (all set to fixed voltage) and connect each one to a MTH terminal block.
3) Each terminal block is connected to about 10 blocks of Atlas track using the Atlas terminal track sections.
4) Each track block contains 8-10 sections of track and is separated from the other blocks at the center rail only with a plastic Atlas joiner.
5) One siding has a toggle switch to turn power on and off to the center rail. I have not connected any power to the center rail of the other siding. Both show 3.5 volts with no power to the center rail. When I switch the toggle switch on, the siding shows the same 18.5 volts as the rest of my layout.
Do you think I have a problem with the wiring?
