DCS ES44AC Engine Feature Not Working

Does it run a controllable speeds with DCS control?  Are you trying to rev up sitting still or are you saying that when you are moving the prime mover sounds stay at idle?

Yes, John, it runs fine using DCS.  So far I’ve only run it at about 10 scale mph and have not really heard it rev up.  I’ll run it faster to check for the rev up while it’s moving.  It’s the rev up or down feature that doesn’t work when sitting stopped at an idle.  I lied about it being the first engine to have a quillable horn.  I have three SD70ACes from the same catalog that I didn’t realize or remember having  the quillable horn.  I’ll check them out and see if they have the same problem.

I know it sounds odd, but make sure that proto-chuff is set to on.

John, it does not rev up when moving.  The sound remains as if it was still at idle not moving.   Proto chuff switch on or off made no difference.

Larry

Again, does it run at the correct speeds when running with DCS, or does it run at full speed all the time?  Does it respond to throttle control under DCS?

Yes, John, it runs at the correct speeds using the DCS remote or the DCS app on my iPhone to increase or decrease the speed.   No rev up or rev down sounds accompany the speed up or slow down of the engine.  No rev up or rev down sounds when using the rev up or rev down buttons on the remote when it is stopped, stationary (not moving).  

I had an engine that had bad tach reader and it would start to move and take off at a high rate.

Since the tach reader is working, this pretty much has to be the sound/chain files.  The only thing I can suggest is downloading them and reloading them in case they're screwed up.  I'd also consider downloading a slightly different model, just to test and see if that changes the symptoms.

That’s pretty much what I suspected I would have to do.  I have yet to down load files for an engine and load them.   I have done the ones for the TIU so that i could use the wi-fi.  It wasn’t too difficult.  Thanks for responding.

Larry

I was able to download and install the sound files for that engine and it now revs up and down when it’s supposed to and when using the feature.

Larry

I love it when a plan comes together!

This topic was moved the traditional forum to the proper MTH DCS forum!!

I apologize for posting my question in the wrong forum.

John, it took me several tries to get the file loaded in the engine.  Third time was the charm.  I appreciate your help.

Larry

There's a little bit of a "rain dance" to loading the chain and sound files into PS/3 boards.  It's not uncommon to have a miss or two.

I tried to load a different sound file into another engine, but I’ve had no luck.  I think the boards lost something while I was trying to install the different files.  The engine loses it’s address and has to be added back into DCS every time the power is removed from the track and DCS changes it to a different address.  The battery is connected and was at 2.48 volts but the sounds immediately quit as soon as power removed from the track.  I will check for battery voltage at the board connection later on today.  The wiring looks ok but it could be broken somewhere.

Larry, you may very well still have a bad battery. It might measure that voltage with no load but if you were to test test it with a load, the voltage will drop rapidly on a bad battery.

I like to test these batteries with a small 6 volt 100ma bulb to make sure they can pass a "loaded" test.
