MTH Z-4000

The red light flashes for maybe a second and goes off (unless the handles are raised which then red stays on until they are lowered to zero) and the display illuminates instantly.

Did you check the breakers?

I did, none are thrown.

So, getting nothing, though there is power to the track. but handles do nothing, and meters are not illuminated.

Can these be worked one?

Can these be worked on?

Might be an early version transformer.

Try putting a 12-18v light on the variable track outputs, illuminated lock-on or an illuminated car on the tracks.  The Z-4000 has to sense a load on power up.  That's what MTH told me when I bought my Z-4000 years ago when they first came out.  I don't know if MTH modified them since then.

Thanks, Rusty,

So, I have an engine on it, and the engine powers up. But that's it, no meters and the handles do nothing. So I cant move the car.

Which set of terminals are you using? Does this happen with both outer terminals (the two inner are fixed voltage)?

Yes, tried both outside terminals.

I sent you the info in a private email Greg.

Check the build date.

MTH changed the design around 2001 and has no parts for those built before then.

They can be repaired if one of your boards is bad  if boards are available ! I have repaired z4000's before. the shipping weight cost a lot though ! I would not attempt to take it apart unless you know what your doing! let me know if I can help you !
