Sound, but no movement

[philsandy]

As the title says, on a Bachmann 3MT 2-6-2.

There are 2 spring like components on the PCB (arrowed on photo) and one of them has come away from the PCB at one end, is this the reason?

Probably. Depends what you mean by sound.

 

The photo shows a circuit board with a DC blanking plate plugged in.

 

So no DCC sound decoder mentioned or shown. Or a DCC non sound decoder.

 

The spring like thing is an inductor in series with the motor and if its come away at one or both ends the motor will not run.

Thanks Nik.

I took the photo from Bachmann 's website, I am using a sound decoder.

I take it the inductors are soldered in place?  Will need to order a replacement PCB from Bachmann.

The inductors can be replaced by a piece of wire.

Thanks smokebox. I pulled off some wire from the inductor coil, drilled out the solder from the terminal and soldered it back in place. Now runs.
