Hello, first help request and very basic. I bought a German Bundespost Model 8134 kit.
I have assembled a Rokutan small oval to get started with, the controller is a Rokutan RC-02.
I have power to the tracks at 12 vdc.
I have taken the body off the locomotive frame and lightly lubricated the motor and gears. (See attachment)
The engine does not run, forward or backward.
I have tried to find instructions for preparing this locomotive for first use without success and the instructions that came in the kit are not for this locomotive.
Could my problem be the controller at 12 volts as the instructions I do have indicate a maximum of 8 vdc?
Any help would be greatly appreciated.
Thanks
Norm

Does the motor spin if you apply a few Volts directly to its contacts? And then, reverse them?

RudiC, I applied 1.5 vdc direct to the brushes, the motor did not move at all.
I tried to move the wheels and they do not turn.
I can turn the armature and the wheels move when I do that, seems stiff but I have no reference at this small size.
Reversing makes no difference.
