owentherail Posted November 10, 2013 Share Posted November 10, 2013 Anyone know what I've done, I got a sound chip for my blue 31 (8 pin) from biff, it sounds great horns n all and all lights work but it don't move, as far as I can see all wires seem ok. I can turn shaft by hand ok, any ideas folks? Ta. Owen. Link to post Share on other sites More sharing options...

owentherail Posted November 10, 2013 Author Share Posted November 10, 2013 Why don't you ask Legomanbiffo? The chip works fine in other 8 pin locos, the 31 does not run with any chip in but sounds work ok Link to post Share on other sites More sharing options...
SRman Posted November 10, 2013 Share Posted November 10, 2013 That then sounds like one of the wires to the brushes may have come adrift. Check the wires at the brush end then trace back to the PCB to see if anything is adrift. Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted November 10, 2013 Share Posted November 10, 2013 The chip works fine in other 8 pin locos, the 31 does not run with any chip in but sounds work ok This means the drive problem is wholly on the 31, as it is independent of the sound decoder which will drive other locos. Not a DCC problem at all. Put the blanking plug in and try the chassis with DC - 9V PP9 battery if you don't have a DC supply - does the motor run, can you see the driveline turning? If not, then the problem as already suggested above is most likely electrical, a broken connection in the wiring between the socket and motor brush terminals. A further alternative is a fault internal to the motor, anything from a failed brush spring to a detached magnet; relatively unlikely. If the motor is turning, then the most likely fault is one bogie not getting drive. Since the chassis has equal weight on each bogie, the bogie not getting drive prevents movement; the motionless wheels have equal brake force to the tractive force the turning wheels can exert. A drive shaft disengaged from ether the motor shaft or the worm the likely cause. Link to post Share on other sites More sharing options...

owentherail Posted November 20, 2013 Author Share Posted November 20, 2013 Well I can say I don't know much about this kind of thing, I've taken it apart as much as I dare and not seen anything wrong, any one tell me where to look? Link to post Share on other sites More sharing options...
