MTH z4000 Transformer
Posted by musictrains on Tuesday, February 25, 2014 7:24 PM

I have an MTH z4000 transformer that I bought less than 2 years ago.  I have not used at all for about 4 months.  Today, I turned it on and noticed all of my accessories connected to the 14 volt portion of the transformer are dead.  The 10 volt side is fine but nothing on the 14 volt side.  The throttles work fine.  Why did the 14 volt portion of the transformer stop working and has this been a problem with these transformers?

 I have had one for about a year now with no problems.

The throttle controls were a little stiff so I took it apart and

lubricated the contacting surfaces with silicon lube, now they

work smoothly.

I would contact MTH and see if they have any suggestions on

what might be wrong with your 14 volt source.

Did you check the thermal breaker on the side near the terminal post?

I just checked it and it fixed my problem.  Those breakers are not mentioned in the manual.  Thank you so much for solving this stressful situation for me.

 Sorry I forgot about those breakers which are a little hard to see. I had one trip on me in the past or one of my grandsons accidentally hit it. Mine was one of the variable voltage breakers.

 I don't know why MTH did not mention them in the instruction book.

2 are rated at 4 amp and 2 at 12 amp.
