  1. As it seems to have been confirmed above that by removing and bridging the polyswitch one is not invalidating the guarantee, are we now to interpret that this is acceptable and official guidance from Kernow on how to alleviate the problem? I haven't heard anything other than what Paul has advised above. Mind you in the greater scheme of things I'm not that bothered as mine is running as sweet as a nut and performed well again yesterday afternoon in the warm sunshine with 8 up round the garden.
  2. With respect, I don't think anyone has "slagged" Kernow Models off on this thread or seems likely to in the future, in fact they (Kernow) have been most helpful with trying to understand the fault and work out a solution which for them (and ultimately us) won't invalidate the guarantee. The fact that they have gone back to the factory over this, just shows their commitment to resolving the situation as quickly as possible. I suspect that hundreds of models are not suffering the same problem because they aren't run as I do mine with 8 or 9 Bachmann coaches round a garden railway with a constant running session sometimes lasting over an hour. I will say that I am delighted with my D600 now that it works properly and would bet on the vast majority of others being just as satisfied.
  3. I and a number of others discovered the problem last week and found that the only way at present to stop the loco from grinding to a halt after about 10 or so minutes was to bridge the re-settable fuse and take it out of the equation altogether. I have been in contact with Kernow over this via several lengthy e-mails and their response so far is non-committal ( mainly because the boss was in Guildford for the opening of their new shop) other than at present they are in dialogue with the factory regarding the issue. It is clear that there is a problem here which needs to be rectified and in the meantime the only way to stop these locos from dying after a few minutes is to bridge the fuse. The only other question over doing this is that it would probably invalidate the guarantee and that is something else which Kernow have said to me that they are investigating. My D600 has been running faultlessly ever since I bridged the fuse. I cannot really envisage anything is likely to overload either the motor or the decoder with the fuse bridged if it is run normally and at a realistic speed.
  4. Well mine has been running for over 30 minutes now with the same load as yesterday and it has performed brilliantly! Email sent to Kernow to alert them of a possible problem with the polyswitch!
  5. Thank you both for this, I am now about to test D600 round the garden (with bridged polyswitch) and hope there are no blue puffs of smoke! This forum is excellent at times and this has proved to be the case this afternoon. Thank you gentlemen
  6. Good stuff.. I might just do this with mine and see what happens with yours and abandon my plans to return it to Kernow
  7. Looking at the description of what a polyswitch does on the interweb, the symptoms of what is happening when the loco comes to a halt would seem to replicate what the polyswitch does. In other words it restricts the current when it gets too hot to just a bare "leakage" until it has cooled down sufficiently then it restores the current back when it cools down. Maybe the polyswitch isn't up to the job!
  8. Oooh! Maybe it's that which is causing the problem then, maybe the motor is sending messages to the resettable fuse to re-set when it gets too hot!
  9. I'm just wondering if it's worth soldering a wired decoder into it just connecting the red/black orange/Grey wires to the track/motor would replicate the problem.
  10. Probably best not to try then. I still think it is the coreless motor causing the problem to be honest. The loco does get very warm when running and it is known that coreless motors do run hotter than conventional ones. I think this is causing the loco to shut down.
  11. I think we need to get Kernow models involved in this as it is clearly a problem. As I'm about to send mine back I will wait patiently to see what they come up with. I'm enclosing a letter explaining everything I have tried. (apart from launching it at great velocity over next doors fence!)
  12. I'm no electronics wizard but how about removing the capacitor and bridging the gap with wire?
  13. The plot thickens! I have now managed to replicate the problem running my D600 on DC without a decoder (using a Gaugemaster model D power controller) so the problem is definitely with the loco not the decoders I am using. I had the loco running round the layout with the same rake of 8 Bachmann blue grey mark1 coaches as yesterday and although it took a little longer, the loco eventually ground to a halt and behaved exactly the same way as it did with the decoder. I have resorted to calling Kernow models and I'm now returning my loco to them for either replacement or diagnosis and repair. They still maintain that they have only had a small number of people with problems only relating to sound decoders and it would therefore seem that my problem hasn't really surfaced in any great numbers with them so it is very important if anyone else is experiencing problems that they make Kernow models aware of it so that this matter can be resolved once and for all. Suffice to say after the huge success of the Bulleid diesel, this one is very disappointing so far. Once I have received the loco back from Kernow I will report back with my findings. They seem a little shy on admitting that there is a problem and one clearly seems to be emerging.
  14. Just as a matter of interest has anyone on here actually taken the plunge and removed the capacitor like component from the circuit board?
