Decoder QSI, Problems in lights

[axel]

To consult them on the encendio of the lights of a locomotive Atlas, since encinden of a " not traditional " way .No if this way they are all, or I have algun problem of configuration, since it is DCC.
When it(he,she) goes towards the front (horn cuts), the light of the front does not ignite and if her(it) of behind (horn talks).
And when ... it(he,she) goes backward (horn talks), the light of this one ignites normally and that of the short horn remains flushed(passionate) tenuous.
Which are the CV and that you value I have to put him. It is a QSI

OK, I see we are fighting translation.

In all the QSI decoders I have that are Atlas engines, they all have a headlight lit dimly. Until I turn the power (in dcc) then the light comes on bright in the direction I am moving.
Otherwise the light is just dim in that direction.

Is this what you are asking?

I don't mess around with QSI decoders enough to know much about them other than to program their addresses in.

Hi ... making the question again.
My problem is with the lights of an ATLAS LOCOMOTIVE (GE B23/30 high nose).
I see that the lights turn on in a no traditional way, if not, I should have a problem with configuration with the DCC.-
Puntually the problem is; when the locomotive goes on, the front light (short nose) doesn´t work, but the back light light correctly (large nose). In the same way, if the locomotive goes back, the large nose light well but the short nose appears very tenuous.

Finally, my question is; having a "QSI" decodif., do you know which cv´s I have to change and the values.
Thanks.

[CIOR]

No, I don't know what CV's. Do you have a manual with it?

From what you are saying:

When you start the engine and move it forward the short hood lights go off, but the long hood lights are on?
And opposite when you run long hood the short hood lights are on and the long hood lights off?

First, you should try resetting factory defaults, if you haven't made a bunch of important CV changes.

There are a couple of other things I can think of, but to give you the right answer I need a bit more information.
Are you operating on a 2 or 4 digit address?
Did you make any other CV changes, if so which ones? The reason I ask this is because there are a few CV's in the speed table that will alter lighting functions if you do not change the right values in CV 29.

The other quick and easy thing you might try is swapping the drive motor wires around, it sounds like they are hooked up in reverse of what the decoder is operating. A mechanical solution, to be sure, but an easy one.

The direction(address) is 4 digits , do not touch CV.

[axel]

4 wires of the lights is it necessary to change?

[railfanalex]

No you do not have to do that. Program CV 29 to a value of 35.

[axel]

I do not work.
Now when I put ahead(forward) it(he,she) goes backward and when pono backward it(he,she) goes ahead(forward).

[railfanalex]

Yes, that does happen. But do the lights go on in the right direction?

If the lights are working right, then I would leave the locomotive as it is now. If it still does not work, as far as I know the only thing left to do is to rewire the lights...

Being a high-hood loco, which end is set up to be 'front'. It may all hinge on that definition..........
