Programing issues on a K-Line TMCC 4-6-6t

If you didn’t get a whistle blast when you hit set, then something isn’t right. The whistle blast acknowledges a set. Are you sure you have the parameters set right in the remote? If the locomotive has been boxed for a long time, you might try taking the shell off and re-seating the radio board. When you put a command engine on the track, and the switch is in PGM, the whistle should blow when you press set. Then when you turn off track power, switch to Run, power back up, the locomotive should wake up when you address that engine, ….blow the whistle, or clang the bell, or move the throttle, or just power up, and the engine should wake up,….and respond to commands…..

This is the clue your feature code is wrong and needs reset-"When I change directions the reverse headlight goes on and off.  The engine runs in reverse with e the reverse headlight off. "

That is directional headlight function as seen in a diesel- but this is a steam engine.

TO RESTORE TMCC FUNCTIONS:
STEP 1: Move switch on loco from RUN to PROGRAM
STEP 2: Turn on Command Base
STEP 3: Place loco on track, then turn on power to track
STEP 4: Press "ENG" then input loco ID#. Press "SET".
STEP 5: Press "ENG" then input loco ID# again.
STEP 6: Press "AUX 1", then input the reprogramming code number than corresponds
to your loco (See list below). 4 for Steam
STEP 7: Turn off power to track, wait ten seconds.
STEP 8: Remove loco from track, move switch from PROGRAM to RUN.
STEP 9: Place loco back on track. Turn power on to track.
STEP 10: Press "ENG" and ID#, then operate as normal.

**REPROGRAMMING CODES**
CODE -- Product & Functions
0 Steam w/ signal sounds
1 Diesel w/ signal sounds, all Legacy Steam engines
2 Diesel w/ Cab light and signal sounds, all Legacy Diesel engines
4 Steam w/ Smoke / Pioneer Zephyr, M10,000

Additional K-line cruise programming is in that document, but I would get the feature code set in the R2LC first. https://ogrforum.com/...-k3380-1361cc-manual

Vern, if he’s not getting an acknowledged set, the feature codes are irrelevant until that happens, ….no?….the radio board doesn’t care about feature codes until it’s awaken to do the task, ……correct?….so either the sound system is having issues, and the feature codes are askew, or something ain’t right with the radio board out the gate?……yes?..

FWIW, wrong feature code set in the R2LC can affect BOTH sound not working (due to incorrect serial data format) and headlight working like a diesel are combined symptoms.

Again, knowing in most TMCC engines of this era- the headlight is directly off the R2LC and the user just got the engine, never ran it, and recently set or attempted to set the ID- but clearly did not reset the feature code, and afterwards, the result is incorrect headlight function and then secondary , lack of sound acknowldegement,  but even more so- K-line Cruise also needs valid serial data for correct operation.

This isn’t entirely correct Vern, so FWIW, my Kline tank is on track within arm’s reach, …no matter the feature code I set, I was acknowledged a set with a whistle blast. So again, if CJ ain’t getting a whistle blast when he hits set, then perhaps something is wrong with his sound system. You’re correct he should attempt a reset and enter the correct feature codes to be sure, but I just tried it with my Kline Cruise equipped 100% stock tank engine ……no matter the feature code, I was greeted with a whistle blast ……FWIW …..😉

There are 2 problems here;

1,) no sounds. Likely a bad 10K ohm pot. Or a bad rs power board or a bad rs audio board. I very much doubt the 8 ohm speaker is bad.

2.) the motor driver could a failed set of triacs or fets. If it hss K-Line cruise, make sure you have the proper aux code entered. 74 or 8 will work (if you have the k-line manual check to make sure it doesn’t require a 0 at the end. Once the aux code is set and it still only runs in reverse, then its a bad motor driver.

use an ID number other ghan 1, like 2 or 5 or the last 2 numbers of the road number to make sure its not some remnants of a previous lash up as engine 1.

Thanks for all the helpful info!  I did a TMCC function reset with no luck.  Just to give a more indepth description of what is going on I did notice the directional lighting is working fine now, the smoke unit works great, the market lights are on, the engine only runs in reverse with the cab 1, no sound, and for heck of it I tried programming it in my DCS system but it didn't respond at all. Should I try resetting the radio board next?  If so, how do I do this?  Or should I try doing the cruise control reset?  Sounds like the radio board should be the next step.  What do you guys think?  I bought the engine from Trainz on Ebay.  I thought I would see if I could take care of the problem myself before I contacted them.  Thanks for your help!

One last attempt.  I tried running it in conventional and other than the headlights, and marker lights coming on it did nothing.  Also I tried in TMCC one more time with the same results, only this time the headlight was flashing.  I turned it off and tried again but this time it was working just as it was before, no sound, running only in reverse, and the headlight was not flashing

I did the programing sequence with both 74 and then 8, and also adding a 0 to to each 740 and 80 with no luck.  Adding the zero caused the engine to go in reverse at full speed like it was in conventional mode at 18 volts.  It also lagged when the throttle was lowered which made it very jerky.  I will contact Tainz about the issue.  Thanks for all your help.

C.J.,

I agree with Mikado. Sounds like you have a couple issues going on. Assign the loco with any ID other than 1. Then set the AUX1 code to “4”. Power up the track and address the engine. The headlight typically blinks. Hit set again and you should get sounds. No sounds? Then start by slowly adjusting the volume pot and listen for faint/muted sounds or crackling/static. If nothing at all, try swapping the power board out if you have an extra to use. Lastly, swap the RS board out. If nothing still, could be power wire to the motherboard or the speaker itself. Check the wires on the volume pot too. They break but the heat shrink holds them on so they look like they’re still connected. Also check the wires at the board connectors. I’ve had a few repairs that had broken wires at the crimp connection in the plug. There’s a little bit of troubleshooting but it can be fixed.
As far as the reverse only condition; when you start up in TMCC, does it sit idle when you throttle up and it should be going forward? Or does it go in reverse regardless every time you press the direction button? Either way, it tells me it’s the motor driver board. Those are known to flake out. I just bought a K-Line 4-6-6T from Trainz last week. I pulled the conventional electronics out to install legacy. It’s the same motor driver board. You’re more than welcome to it if you want to pay postage. It works fine.
Can you post a pic of the electronics?
