I get no output power to track. Lock on won't light up. What the heck could it be? I never had any issues before. Now all the sudden I do!
I have the older tiu. Not a rev. L version.
Thanks for any help

take the cover off and check the internal fuses if it has them some of the older ones did not have them.

which version is the tiu the rev is on the bottom of the case!please show us a picture of the bottom of the case! also do you use it with a remote or only use as variable control?
Take your remote press track select TIU and then check channel to make sure it is on (scroll thumbwheel) to increase voltage and not accidentally shut off or voltage lowered and also softkey will allow you to make channel variable or fixed setting.
Just to make sure we're on the same page...
You MUST have power on the input to a specific channel in order to have any output voltage. Just making sure we're not expecting otherwise.
When you apply power to the TIU, do you see the light blink once to indicate the TIU address? If you power the fixed #1 input, can you run DCS locomotives using the fixed #1 output?
I run my TIU with the variable channels configured in fixed mode. That allows command operation normally, and they'll revert to variable if I select a track and vary the voltage.
What are you using for power into each of the 4 channel inputs?
Are your variable channels set to fixed or are you scrolling up power to them using the TRK screen on there remote?
Did you check all the fuses (in the TIU or external) and circuit breakers?
Chris,
Power your TIU thru the Aux and see what happens.

you always get a red blinking light n the tiu on power up , should blink 1 time when first turned on.!
Alan
You always have to have power either fixed input one to power up the tiu control circuits or the aux power input! either input will power the tiu. if your using variable one or two you need power at one of those inputs.
But remember if you power fixed variable voltage 1 in you must have power also to either fixed voltage in or aux to power the tiu electronics!
Alan
you should buy barry's book it explains everything you need to do to run DCS or variable control form your remote and has all the requirements and what to check in detail when you have a problem such as you do ,will save you a lot of time troubleshooting by using the DCS COMPANION!
Alan
Kind of sounds like you're not powering up the tiu . The TIU need a power supply to turn on, operate /function.
2 ways to turn it on.... power to fixed 1 or an aux power supply
. Nothing works unless the tiu is powered up...Fixed 2 is a straight through connection so even though power flows through it the tiu is still dead and there's no dcs signal. The Var channels are also dead.
Bottom line make sure the tiu is turned on by checking out the led on the top of the tiu.
nope!
Chris,
You MUST power the TIU from either the aux power input or Fixed #1. You will never get any output from the variable channels unless one of those two power sources is connected and active.
Chris,
From page 95 of The DCS Companion 3rd Edition:
Providing Power to the TIU
Like any other electronic component, the TIU requires a power source. MTH designed the TIU so that it can be powered in two different ways.
One way is to use the track power that is present at the inputs to TIU Fixed Channel #1. This power source is
available whenever the O gauge operator is running trains on tracks connected to Fixed Channel #1.
Another way to power the TIU is to use a separate power supply that is plugged into the TIU's Aux. Power port. In this case, the TIU would have power all the time. Any power supply that provides between 12 and 22 volts AC or DC at 1.5 amps or greater, equipped with a compatible barrel plug, may be used.
If the TIU is a Rev. L (or later) that has a USB port, the TIU may alternately be powered via the USB port. However, this should only be done when using the TIU solely to update TIU or DCS Remote software. In order to perform DCS engine sound file transfers, DCS Remote backup or recovery, DCS engine operation, or activation of switch tracks or accessories connected to a TIU's AIUs, power must come from either the Aux.
Power port or Fixed Channel #1 Input.
When the TIU is powered through Fixed Channel #1 Input, every time the power to the tracks controlled by Fixed Channel #1 is interrupted for any reason, the TIU turns itself off. However, when the TIU is powered through the Aux. Power port, the TIU remains turned on regardless of the state of power applied to the tracks controlled by Fixed Channel #1.
This and a whole lot more is all in MTH’s “The DCS Companion 3rd Edition", available for purchase from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!
Guns,
This is the exact reason I advised him to power thru the Aux, it eliminates all the problems and affords immediate shut down with the E-Stop at the same time.

Can you determine whether it's a faulty tiu Fixed 1 channel or a wiring issue with fixed 1's track.... Disconnect fixed 1 out and see if anything blows....
How many power supplies are you using and what channels do they power including the aux power. What are they??
Chris D,
When you powered the TIU thru the Aux, did you try running anything on the Fixed one Channel/track, it sounds like you have a bad channel or you have mis-wired that particular Fixed #1 Channel/track.
