  1. I see once again the 8F has been pushed back again, it was supposed to have been here in June/July, it then got pushed to August, now August is here its suddenly been pushed back to October, will this be yet another year the 8F fails to arrive. They sure know how to string their customers along. :(

  2. One thing often recommended when fitting TTS decoders into Bachmann Diesels is to insert a resister around 500 ohm to 1k ohm IIRC into the blue wire as Bachmann locos have more demanding lighting thst is known to overload the TTS decoders, not saying that is behind your problem but something to do with the replacement to be safe. 

     

    I had one die in a Bachmann 66 because of it.

  3. Hi

     

    I removed the complete PCB on my 14 and 08 and the slow speed running was vastly improved, its only held in place by two solder joints so easy to remove, you then just connect the orange and grey wires to the two points where the PCB was soldered.

     

    a simple job well wort doing.  the hardest part with the 14 is routing the wires so they don't get crushed when the body is refitted, IIRC they need to be routed down the side of the chassis not over the top.

    Keeping it "dumb",  then ignore the post by Paul on the Buck Converter.  

    If you use a DC power supply, then you can ignore reverse voltages stuff.  

     

     

    1 - your LEDs need a resistor, one per light.   Calculator suggested by trevora is OK,  or,

    if you have a 12v supply, you could start with 2kOhm (2000 ohm) and drop to 1kOhm if that's too dim. 

    if you have a 5v supply, start with 470ohm, and drop to 220ohm if too dim. 

    In both cases, increase the values if too bright.

     

    2 - power supply.  Go with something DC, between 5v (common) and 12v (common).   A simple "wall brick" will do, such as an old phone charger or similar - read the voltage off its case, 5v is very common for chargers.  

     

    3 - how many per power supply ?   A typical LED is maximum 20mA =  0.020A  .    So, a 500mA power supply would be theoretically able to run 25 at full brightness, or a 1A power supply could run 50 at full brightness.  In practise, add a bit of "headroom", so 40 on a 1A supply.   If running at lower brightness, then you can run more.

    Or keep it really dumb and ignore Nigel's post as well :nono:

  5. You could also run your lighting from a 12v bus using little Buck converters, something like this will do the job

    If you have a few of them dotted about your layout you could also have the levels of the connected LED,s adjusted to give the best lighting effect for the area they are in.

     

    I have them on mine and they work well.

  6. You could always PM the answer to those that took the time to try and help.

     

    You might not 'remember all the questions but I bet you remember what button presses worked.

     

    Bit pointless asking for help then not sharing the solution 

     

    Some on here are getting old but still have long memories for this sort of thing ;)

  7. IIRC eBay buyers can have up to 3 months to report a problem and there was talk of them extending it to six, something to do with EEC rules on distance selling.

     

    I had one were I sold a Farish Deltic DCC fitted, the buyer left positive feedback, do I left him positive feedback.  A month later he started a return saying it's derailing, which I accepted, only when I got it back the buyer had removed the decoder and kept it.

     

    EBay did nothing and refunded him in full.

     

    There are those who know how the system works and when to work it :(

  8. Like the parcel I sent to a guy in Luxembourg as in the Grand Dutchy of Luxembourg, it got there eventually but Royal Mail sent it via Luxembourg America?

     

    Still back on topic, sounds like the OP has been provided an incorrect tracking number or the sender is trying to pull a fast one, not an eBay item by any chance ;)

     

    Double check with the sender
