Do these chuff switches just fail and quit altogether when the engine loses chuffing sounds or the chuffing sounds drop out intermittently.
what I guess I want to know is do they just go from working to not working so to speak.
my 4-6-0 ten wheeler I just repaired the ir sensor on. when I had a chance to run it a bit. was dropping chuffs at random sometimes.
I hate to open it back up to replace the chuff switch if it is not necessary. thanks.

Chuff switches can just randomly fail. Where the chuff switch lives in relation to the smoke unit is one factor that can kill a switch in short order. Smoke fluid can turn to varnish, and render a chuff switch useless. However, in your case, I’d take a closer look at the IR parts again, beings you’ve just done some sensor work. Chuff can drop out intermediately if the sensors lose sight of one another,…….a tell-tale of such a condition is if the chuff sounds operate as advertised on straight track, but gets interrupted on curves. Also, grades can play a role in IR sensor alignment. ……I’d take a harder look at the IR sensors on that particular case if I were in your shoes…..

thanks pat.
pat, the IR was good and aligned. no bad wires. turns out it was the chuff switch. it was hidden under the motor in the back.
it was a real pita to get to it,but I managed to get it without breaking somthing else or a wire off.
took it out and adjusted it and reinstalled it and wala magically it works fine now. those droped chuff sounds were annoying me so I had to fix it.
if only lionel still had the ac reg boards 😡 it would be good as new. oh well it is what it is. at least it runs good. thanks again pat.

I thought John had a patch board to make the smoke work again?….
Pat
I my other post I think he put a link to that board he made. so you would be correct,but it is way beyond my skills. I was thinking he made it for himeself. I will have to revisit my other post.
I got this engine used and still with the IR part and a new cow catcher part. it is a good deal. sinking anymore into this and the good deal is not looking so good. although maybe I should look into johns smoke fix as a steamer that does not smoke is no fun to watch at least for me.
The board I made is all designed, so it's pretty easy to assemble and use.
