If you claim to be a certified MTH tech why would you do shoddy work. I bought an MTH union pacific coal turbine set that was said to have been upgraded to ps2 3 volt. It has two stickers saying it has been upgraded. It obviously has been since this originally was a ps1 engine. My bad luck is the MTH tech upgrader/ installer did lousy work.
First I noticed he installed one of the smoke units backwards. Then the tether on the lead engine was just done so poorly three wires just fell off and black tape was used to insulate the tether. I found this out after hooking up all three units and trying to power up the track. It immediately blew the 180 breakers. So I removed it unit one at a time to see which unit was causing this.
Then discovered it was the lead unit and the poorly done tether. This may have cooked the board although I can not say for sure. I like this model and it weighs so much I hate to return it to the seller. So I will bite the bullet and let my tech repair it properly.
Going forward when a seller says it was check or upgraded by an authorized MTH tech what questions can be asked or how can a buyer know if the sellers tech is good or bad so as not to get burned.
Its not the end of the world here, but it sure sucks and is very disappointing.
