Howdy,

I picked up a Z-4000 at an estate sale company. It looks like it has hardly been used. It runs the trains well and the accessory power seems ok. One concern is that the voltage does not go to zero on the LED displays when the throttle  handles are down to zero. They display 2.0 and 2.3 on the left and right sides. They drop to about .5 just by placing a post war 2065 on the track. (Testing each separately.) Picture of no load state attached.

I did read in an older thread where GRJ suggested it was OK to live with it that way. There was some disagreement from others on the thread.

Any thoughts on running it as is if and until other problems present?

Thanks in advance, Bill

I believe this is relatively normal for this transformer where small voltage leaks are common. If it were higher or prevented you from shutting down a command control engine, that would be problematic.

An easy solution is to install a lamp or lighted lock-on on the track and that should bring the voltage reading down to zero or near zero when you put the handles all the way down.
