Hi everyone!
Just today I noticed that one of the two 9V motors that power a Santa Fe engine each does not work. I have no idea why since the light of the affected engine is on. So there is electricity going through the cable that is attached to the motor at one end and to the light brick at the other. But the motor doesn't move. If you push the motor, it stops after a few centimetres... if you are lucky... although the speed regulator is set at full speed. And even it it moves for some centimeters, it isn't fast.
I have no idea as to what could cause the problem and how to solve it. Just several days ago it still worked. But as I said: Electricity seems to go through the motor, otherwise the light brick wouldn't go on.
