MTH Z-1000 Voltage Leak

To be honest, I've yet to find a MTH-Z controller that was ever right on the money. Is the "leak" when the controller is at full power? If so, after how long? Since the loss is so minimal I wouldn't worry about it. IMHO

No this is turned off and leaks about 3 volts. I've got many other Z Controllers that are perfect but are being used so I can't swap them out. This one I really want to be "off" as it is running accessories, including several smoke units. If I put it at off, it should be off. 

Now I understand. You failed to mention your intended use. That being the case, your problematic controller should be returned (is possible). If not possible you can use a accessory strip with a on/off switch for protection. If push comes to shove you can buy another controller (a pain) This is a new one on me as I've never experienced anything like it.  

For $5 or less, sounds like it would be an easy fix.  I have all my transformers, etc., feed in a surge protector strip with an on/off switch.  When I am through playing with the trains I shut it all down with one movement of my index finger.  Also gives me a little piece of mind when a thunderstorm is brewing outside to know the trains will be all right...generally speaking.  3 volts should be easy to work around and adapt.

Another easy fix is to buy a single pole on/off switch and connect it between the transformer and track power in one of the wires going to the track. Wire it in series with the hot wire to the track and that should kill the power.

Since this is a new old stock, it is NOT a new feature.  Yes some controllers could go bad and bleed a dc signal, which can cause issues with operating.  G

I've asked my dealer to swap it out for a better one, something I'm sure there won't be any issue with. I will also test at the store prior to heading home. 

Thanks all.
