Reply to "MTH TIU does not work/red light is off - but unit has power to fixed in (1)"

If the red LED isn't lit then the TIU is not getting power for its own use.

The TIU always passes track power straight through both Fixed #1 and Fixed #2, however, if the TIU isn't powered there will not be a DCS signal at the channel's output.

Three questions:

Is there anything plugged into the TIU's Aux. Power port?
Has this TIU ever worked?
If the TIU has worked before, what's happened since the last time it did work?
