Merry Christmas everyone!
Am hoping someone can point out what I'm missing here. Am trying to hook up a Z1000 brick through the TIU to power thetrack and getting nothing to the track. Brick seems OK and I see a small red light inside the TIU so assume its getting power.
Brick wired to Fixed 1 input and track wired from Fixed 1 DCS out. Is this correct please?
First time trying this without the Z4000 in the mix...
Thanks

You can't set the fixed outputs to variable, you can only set the variable outputs to fixed.
Nice to find an easy one for a change. 
Another question - Does the TIU have a fuse inside perchance?
Was running our Legacy Mikado and as it was reversing, the coupler briefly shorted on the center rail. The breaker tripped on the Z1000 and after a reset the TUI seems 'dead'. Taken out of the loop, the Mike is running again...
Yes, there are 4 fuses inside the TIU, one for each channel.
This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!
Thanks Barry. Is this 'normal' to happen like this? I've had this same DSC system operating without a glitch on our layout though numerous shorts for 3 years.
All I have set up here is about 8 lineal feet of track with the single Z1K, the TIU, and a Legacy base.
It's possible that the internal fuse blew. you'll have to open it up and check the fuses. They are automotive blade type fuses-- easy to spot. I've been using my rev G TIU wih external for years. Z4000 usually trips before fuse blows.
Sam,
Is this 'normal' to happen like this?
Fierst, define "normal".
Any fuse can blow, however, if you have other external protection of 10-15 amp fusses or circuit breakers, they should typically blow or trip before the 20 amp fuses in the TIU.
If the internal 20amp fuse is blown and the TIU is not being run by aux power the whole thing will not work. It is possible to blow both the 20 amp fuse and the 1000 breaker at the same time.
If the red light is on in the TIU the 20 amp internal fuse is good providing you are only powering the TIU through fixed 1. if the light is not on you need to remove the TIU cover and inspect the fuse. If you need a fuse and do not have a new one you can take one out of one of the other spots or take a 20 amp out of your car. Do you really need windshield wipers when you are running trains.
