Steve,  Power this up on a test track conventional only, with the volume turned up all the way with the pot.  If the engine starts loud,  than goes to half volume on it's own conventionally, you may have a board hardware issue. 

 

If so, the board needs to be tested to eliminate issues.

 

If this is just certain sounds and the reset are loud and fine, than I would reload the sound file.

 

I would say I have seen speakers go bad and effect certain tones more than others, but that has been the 16 ohm speakers that had metal flaking.   Not 4ohm speakers with the 3V boards.   G

Well,  The conventional test is easier than all that.  As far as the speaker, it was in reference to different sound levels for different tones.  Really all depends on what is actually happening.

 

It is easy to turn on power and than turn off power and listen for proper shutdown.  No need to open engine yet.  G

 Probably un-related. My outdoor RR is going bizzerk.

I just tried again to get things better and a Aristo CN Dash9 with PS2 was silent? It had acted up all night. It seems that I can't get more than two engines in a block. I need to work on strength although I'm getting all tens??

 Anyways I figured I'd blown the amp inside because I got the engine working, just silent. All lights and control was working. As I pulled her off the track for the third time giving up for the night, the speaker belted out the engine's shutdown sounds!

 At least I'll guess the volume probably got muted. I had tried to turn it up while in a lashup, by addressing it individually. No go. I had noticed that other parameters were set wacky like acc/ and dec rates the other day so I bet the engine's sounds got muted.

 I have high hopes that there's nothing wrong just a control problem. But for some reason, the whole outdoor RR is not reliable. I'm going to try and remove the electronic filters tomorrow and try bulbs at the ends of the blocks.

 I ran the O scale the other day and everything worked with 4.3????

I've ordered another new "L" TIU and hope to get the RR tuned up and reliable. Sorry for the babble but I'm wondering if others are struggling with these same issues??

John,  I guess his symptom description isn't good enough to help for sure.  First, even with no battery installed, he should be able to adjust the engine sounds while powered during his operating session.  The engine will take a factory or feature reset while power is applied.  So during normal operation he should have all sounds as he sets them.  If he can't do that and a factory reset doesn't work, he has a more serious issue.

 

If the battery is bad, or worse a hardware issue with the battery circuit, I would agree that the engine won't remember the settings and revert the sounds.

 

From the initial explanation he can't get the sounds to play right while powered.  So that is either a hardware fault, or corrupt sound file.

 

We all are just throwing out ideas, without enough specific symptoms to really figure out what is wrong.

 

Before I would try reloading a sound file, I try to isolate the issue via simple test.  Conventional versus DCS, Feature and Factory resets, Battery circuit shutdown test.  G
