Decoder issue

 
  NSWmodeller Beginner

I've recently installed a Loksound Direct Select decoder into the latest Powerline Class 48. Here is my issue which has me scratching my head:

1) Decorder can be programmed;
2) Lights work;
3 Sound works;

But, when I go to run the engine, nothing happens.

Other information:
- have checked all connection, all looks good
- Have pulled out moter and checked against a 9 volt battery, all is good.
- when sound is activated and throttle increased, the sound goes through its pace as if the train is running

Scratching my head as usually if a decoder is dead, nothing works.

Any suggestions?

Thanks in advance

Gday NSWmodeller,
I would asume that the Lok Sound has been hard wired in, I would be checking all the solder joints with in particuler the ones on the motor, maybe a dry joint.
Another thing to try would be to play with the CV's that control the motor kick, may need to increase these to get the motor to run.

Question from a DCC newbie, what does setting CV 19 to 0 do?

When you say sound and lights work only idle/rev up ? horn ? headlights on and off??

Do a reset and then the locos number will revert to 3

Factory reset of CVs:
Set CV 8 to 8. This will set the CVs to the values listed as default in the LokSound Manual, which differ in some cases with the values programmed into the decoder for a given locomotive sound.

CV 19 is for locos that have been in a consist and were removed from a layout it assumes the leading locos number.

Hi All

I have the same issue with a V3.5. Funny thing is it works on the Sprog II and test track.

Any suggestions cause it sounds like NSWmodeller is having similar issues.

try F stops 5 or 6 of F8

Ive got a v3.5 with a NR sound installation  from him and now from memory something like this happened .

Sorry Anzac..maybe I should have mentioned I am on Easy DCC.

I haven't fitted a Select to the PL 48, only a few of the V4 decoders. The model has an extra PCBA that is connected directly to the pickups, not the decoder. I've found the decoder had programming issues when the board was part of the equation such that I couldn't reflash the decoder with the board connected. The board converts DCC to DC to power the fan and cab light. The board can be taken out and the cab light and fan put onto Aux1 and Aux 2 easily enough.

NSWmodeller - have you been able to get the model going as yet?

Your Function buttons are just your numbers 0-9 try them might be lucky

Hehehehe, in lay terms, it removes the loco from a consist and I am quite certain it'll make this loco behave as expected.

I know you have checked but check the motor wiring carefully at the motor and on your decoder. It is possible a wire has come away from the motor even though you may not have even done any work there. Have you soldered the motor wires to the board or used the little black plastic slide on clips to attach the wire as sometimes they might not make connection properly.
If still a no go, I would remove the board and motor from the loco, re-connect motor wires to the board(check connection on motor) then clip pick up wires to your test track and connected them to the board. Apply step 1 on your throttle or more if needed to see if the motor will turn. If it works great if not least you know your problem is in the decoder itself.

Good luck

Tried that..didn't work.

The head lights work in forward and reverse;
Horn works;
Bell works;
Everything works except the damn motor.

When the throttle is increased the sound notches up, but the motor does not turn.

Did the reset..issue did not disappear

Took the old board out and replaced it with the Loksound Select Direct decoder, it comes with a new board and decorder in one. Got everything going except the motor. Re-solder the board tags and the motor tags but did not help.

try the decoder in another loco, jerry rigged not proberly installed that is.  Aleternatly  try  unsoldering the two wores to the motor, and hook up to 0-12V to ensure motor works, then try another decoder with just track and motoor  connected, a non-sound one best.

Need to determine if it is loco, decoder, or setting of decoder. There is been great advise so far. Let us know any outcome....

boy you guys have been busy as I was editing my post several new posts have been added. NSWmodeller have a quick read of my earlier post, about 5 mins ago.

Thanks Captain, I went the other way and got the Select Direct board and decoder so went of the following instructions:
http://members.optusnet.com.au/nswmn1/48Select3.htm

Pretty much have done all that, even took the motor out and tested with a 9V battery, the motor worked fine.

I don't believe there is anything further I can try that I haven't already...I believe its the board..although I'never come across a decoder where by everything works but the motor. Usually if they are dead, then they are dead. I even set CV 52, 53, 54 and 55, just in case something was astray when the board got reset.

How about an auto calibration of the motor?

Put the loco on a stretch of track, say 2m long. Ensure F1 is off. Enter a value of 0 into CV54, exit program mode and then press F1. The loco should rocket down the track and come to a stop.

If this fails then check that you haven't got manual notching (down) engaged, which can stop the loco from moving off.

If this doesn't help, then perhaps the decoder is cactus. It does happen time to time.

Is the motor wire a single strand wire, it could have broken inside the plastic insulation. Try replacing them

One other thing that could possibly be wrong, the gearing is not jammed or something is stopping it rotating. If you know the motor works then check the gearing it might be stiff enough to stop it. A wild punt but it could be it. Also good advice about the wire as well you can get a broken wire in some set ups. I have had a few over the years with broken single strand wires.

That's why I suggested to remove the decoder and motor from the loco and wire it up on the work bench to eliminate that possible cause because you are right that can happen. Not sure if NSWmodeller has actually  done that yet but he seems to have tried everything else with no luck.

NSWmodellers problem sounds exactly like mine, however do you have an explanation as to why my loco would work perfectly on the SPROG II and not the layout?

NSWmodeller, have you a SPROG II or do you program on the layout?

Also to NSW modeller...

Does the model have those twin caps attached?
Does the motor turn when regular DC is applied to the rails?
Check values of CV 3 (accel CV). If it's at a maximum, the loco will take a minute to move.
Check value of CV 29 (directional bit).

Though it does sound as though you've not mucked around with CVs ex factory, so it should just work.

I've found on O scale models the massive motor cap can stop the motor from moving at all. I understand that the caps work ok with the Powerline decoder, but it may be worth disconnecting them if relevant to the 48 class. The LS decoder will come with noise suppresion hardware on it anyway. Also, that fan and light board may be worth disconnecting too - I reckon it muddles with decoder programming. This issue is a little strange, as there's absolutely no signal getting to the motor by the sounds of it.

I don't use an SPROG programmer or Select decoders much, but it may also be worth asking questions on the Yahoo Groups LokSound forum.

Does the motor "jump" when any CV is changed?
