I recently purchased a used MTH NJ Transit Alp 44 pronto-sound 2.0 (MTH 20-5529-1). In DCS mode the bell and whistle will not work, no crew yard chatter, and no PFA sounds. When track power is turned off the engine has sounds for a few seconds. I replaced the battery with a new one from MTH. I tried a feature and factory reset from my DCS Commander and still can not get any sounds in DCS mode. I am open to any suggestions at this time.

Check speaker and speaker wires. G

Roger that. I've got 16.2 Ohms at the speaker, and at the end of the harness connector. No sign of shorts or insulation damage What next?
I took the cover off the speaker cover and pulled out the speaker about a 1/2 to see if there was any damage to the speaker, no damage was visibly found. I remounted the speaker and place the engine back on the tracks, in conventional mode I now get sounds, but engine will not move in conventional mode no matter how much I throttle up. So I now go to DCS mode and get intermittent crew sounds ,Bell and whistle now work intermittent when buttons are pressed on DCS Commander, its like sometimes there is sound and sometimes not. When I removed the cover earlier l looked carefully for any pinched grounded wires and found none. I guess my dislodging the speaker and replaced in back into position must have moved something around that I am not aware of to get the sounds back. I am still scratching my head and desperately trying to get this engine to work as per specs. I'm sending out a SOS to the members, any suggestions? Where do I go from here?
Can be broken wire under insulation so check carefully. Also did the speaker have gray powder around magnet. Since 16 ohms I assume this is a PS-2 5V, did not look up the engine. Those speaker were susceptible to disintegrating magnet. Also, I have had a fair amount of speakers that ohm correct but do not work under power once coils starts vibrating. SO try a different 16 ohm speaker. G

Yes, the speaker had a lot of gray powder on it, so I will order a new speaker from MTH and I'll go from there. Thank you.
GGG, you hit the nail right on the head. It was the speaker, I replaced it and its working as intended. Thanks again.
