Thanks everyone for all of your ideas. Checked batteries in the remote and all 3 were at 1.54vdc. So I put 3 new ones reading 1.61 vdc into controller. No change.
The only switch is for controlling the sound board. Maybe a speaker off switch??? But it does silence the diesel sound.
Just so everyone knows the sound is linear with the speed controller knob. The higher speed increases the speed of the sound. Carl. Addressing your comment about changing the controller. Yes that would be nice but I know of no one that has a diesel remote. But logic is telling me that since the sound is increasing in the diesel that it must be recognizing the rf signal change since it's volume and speed is changing relative to the controller knob being turned up in speed ?!?!
Because the question was asked, yes it is the only engine on the track. And I also disconnected the 10" straight piece that has the wall wart female plug from the rest of the track so as to isolate it. I do get 14vac across rails by the way. Still no motion of diesel.
So the last three items suggested is that of applying voltage to the motor jack directly, checking for a jammed gear box because of the eye movement contraption, and jammed side rods.
It's going to take a bit to check these, so bare with me. As I'm going to have to take it apart again. I did notice when I previously tore it apart, partially, in order to check the wiring and brushes that transfer the atoms to the axles, that the eyes did move when the little lever coming out from the front of the engine cowling was moved, but I wasn't really moving it in the entire range of motion that it's probably cable of. Likewise the side rods were allowing wheels to rotate but that doesn't mean I didn't jam it some how when putting it back together. So I need to tear it apart again and check the gearbox.
Carl. You suggested applying 3-5 volts DC to the motor directly. Or even a 9 volt battery. So this tells me (can't say I thought about it until now) that one of the two circuit board is also rectifying the ac to dc. There appears to be a small pcb attached to the motor. Do you know if this is the ac to dc rectifier? Or is it on the big PCB board? I couldn't see too much of the circuitry on the motor board but I see there are two resistors. So the only reason I'm throwing this out is because I would like to clarify that a dc voltage can be applied directly to this connector in lieu of an ac voltage. Not knowing if it matters. But I'd rather not make matters any worse than what they already may be.
Thanks again everyone for your experience because I have little.
