We have a switching face Thomas that I have been able to get running. That one had a burnt output transistor. I replaced the transistor and got the engine running. However, it ran faster backwards than forwards. It turns out that transistors have a specified amount of current drop. The one I installed for forward had a higher current drop than the one for reverse. I switched them! LoL~! Oh the motors brushes were not touching the commutator either when I got him. A motor cleaning and brush alignment was in order.
Back to the non switching face Thomas. Anyone have any tips? It's been a while since I've worked on him. In fact, I don't know where I stashed the remote! LoL~!
Anyone else repair these engines down to the component level?
There are a couple different year R/C Thomas's, have you confirmed that the years match? I believe there is a 2005 and a 2008. Maybe it is not this, but just a thought. Also under the back wheels in the tender ther is a pressure switch, sometimes I have found those to break.
