Reply to "MTH Z 4000 ISSUE ????"

Afternoon gentlemen, it is Thursday afternoon and I have been able to get back to the layout for more testing.

OK....tried everything that has been suggested so far, with the exception of GunRunnerJohn's advice (I think he is referring to the "special MTH chip" to reset the board) and GGG's advice to swap out a board.....he's starting to scare me now!!

What I've done is a short video of the Z4000, with nothing on the track, and noticed that the voltage drops from 9V to nothing when I lower the throttle lever. When I raise the lever it goes from zero to 9V......nothing in between!!!

I think this may be the root of the problem, The voltage drop is insufficient to trigger the board to leave the reset mode, and it either wants to shut down or go to the next cycle of selecting a "feature" to reset.

Please have a look at the video and let me know your thoughts. (Hope the video works!!!)
