I would not do that. If you do not have a power supply with current and voltage meters, and a basic ideal of what can go wrong you risk having a processor board that will eat your working power supply board. Then you could have two engines bad.
I have never seen this symptom. For the engine to take out the track it has to be heavy damage. When that happens to the Power Supply board it usually means a bad processor too. Take the board out of the engine and send to a tech who does board testing repair. I can do this work, it you don't have your own tech. G
