K-line Alco PA ABA only smokes in reverse - fixed!

Hi Bob,
I wish I could help on this issue, but my only Guedes would be to try replacing the receiver board. I think that is toggling off the smoke when you send the direction change signal via the handheld.

But my main reason for replying ( I know it is selfish) is that I am in process of upgrading my K-line Pa-1Aa with only TMCC and Railsounds to having Smoke and electrocouplers.
I would be indebted to you if I could get some photos of the insides of yours showing the location and mounting methods of the smoke units.
The brackets are no longer available and no one seems to have a photo or illustrated parts diagram. Thanks

Re-program the engine.

I re-programmed the engine as engine 0, but still only smokes in reverse. Under conventional, it smokes in F-N-R.  Also tried a reset Aux-1,0.  Is there any other "factory reset" feature?  Thoughts?

I'll try to get some pictures for you later today.

Hi Bob,
with Switch set to Program.
Press Eng then Eng#.
Press Set.
Press Aux1 8.
That should reset the Receiver to Deisel w/Railsounds and Smoke.
Hope that works.

You also need to pick another # besides 0.
Try 1. You can then change when the smoke unit is working properly.

A little sloppy in my instructions.
Ado not forget to shut off power. Switch back to Run. Turn power back on.
Press Eng, Eng#, I usually press the horn just as a confirmation.
Then Aux1 0 if you want to do a soft reset also.

Thanks Fffreddd (can I call you Fred for short ?). 

That worked perfectly. All is good.

I'm a latecomer to TMCC/Legacy.  These are the little tips you just have to know. 

Bob

Sure. Everyone else does. Too many forums and to many Fred, Fred1,Fred2's, etc.

I had to do the same thing today.
Replaced a reciever after rebuilding the smoke unit on my K-line 0-4-0

Ready to tear it apart again and the light bulb went on in my little smoke fogged cranium.

One of the last resorts before swapping parts.
Now if you can remember those photos, I would be much obliged.
Thx

Bob,

Thanks for the link.   That was going to be my next question.

Here are the pictures of the powered A unit with smoke.

Thanks again guys

Smoke is not supposed to be direction dependent especially on a TMCC RS4 based engine.  It is either on or off.

 

So unless K-line did a mod and used a diode of the motor to power smoke it is hard to determine why smoke goes off in reverse.  Unless the direction change is turning the smoke TRIAC off too.  G

In program mode, the aux1, 8 reset fixed the problem. I guess the programming had gotten scrambled.
Thanks
Bob

That is a weird one, but reprogramming is always the first action. Thanks for closing it out.   G
