Lionmaster BB 4011 Legacy 6-11208

On your Legacy controller try a few ALT1 / "1" key sequences and see if that doesn't bring the chuffing back.

Thanks GRJ. I only operate with TMCC - will the same ALT1 - ! work please?

Since this is a Legacy locomotive, that will work with the TMCC remote as well.

I might be wrong but i don’t think that locomotive had the two different volume settings (it’s an oddball with RS6 board). Still doesn’t hurt to try.

i had the same issue with mine some time back. I had to go in and tweak the lever on the chuff switch so it actually actuated it.

Thanks for the replies guys. I am assuming the chuff switch is fine as it activates the puffing smoke correctly.

GRJ - I tried various combinations of ALT1 + 1 and no difference I am afraid

Anyone got any other ideas - could I have a loose wire/plug I missed?

Thanks

Ah shoot I missed that part. Is the rail/signal switch under one of the water hatches switched to “rail”?

Update on the engine - Yes all switches set correctly. Tried AUX!-1 , tried another reset, but still no progress. Everything is working well except the chuff sounds.

Anyone got any more ideas I can try - Thanks

Try the BB tender on other Legacy steamer with the IR tether, see if you get a chuff.  Trying to figure out which end has the problem.

Update - I couldn't get the IR tethers to line up trying another tender with the BB.  However I was able to hold the BB's tender behind another Legacy engine and all sounds are present including the chuff!

This makes me think its the engine end at fault. I have fitted an new tether to the engine but still no joy. I also tried the "mobile phone camera against the engine tether" - hope I got that right - and nothing.

All I get with the new tethe3r fitted is all sounds as before except Chuff.

So - I assume either I messed up fitting the new tether or something else is wrong - any thoughts most welcome.

I have given up for today.............................

John any chance the chuff signal is getting to the SCF1 but not going past that into the serial data out to the tender? Sounds kinda odd no wiring diagram from Lionel. I have one I could open up 🤔

HI Zach - Sorry I no idea what that means. Over the w/e I will check over my work replacing the tether (it was "new" stock still in its original sealed bag and also go over all the wiring again to see if I can see any pinched wires.loose plugs, which is where I started.

Thank you for your continued interest - we have no techs or service facilities for the big L over here in England.........

That's a possibility, we had something like that not so long ago.  However, if other commands like couplers and whistle/bell/crew talk are getting there, that seems like a remote possibility.

Well having left things for a month while I sulked I took another look today re-tracing all the wires, dismantled the second power unit etc...

I found a couple of pinched wires - now fixed  -and what appeared to be a disconnected earth wire. For the life of me I couldn't see where it went but after "grounding it" to the main chassis using one of the switch screws everything now functions as it should.....sound to match my puffing smoke!!

I have now run the BB for almost an hour both light engine and with a full load and all good.So I am going to leave it there.

Thanks for all the input earlier. Cheers from the UK (the land Lionel forgot!!)

You're lucky that connecting an unknown wire to the frame ground didn't blow it sky high!
