I have a early released MTH Premier PRR Q2 that lost all of its sounds. I have tried all the basic troubleshooting I can think of to fix it. (Reset engine to factory default, replaced the BCR, checked the wiring in the tender for any cut or loose wires) The speaker does not appear to have the delaminating issue that some early PS2 speakers had. The sound board is not in the tender and I don't know what else I can check beyond what I have already looked at. Any suggestions would be great before heading to a service tech.

disconnect the speaker and check for ohm reading. Also connect the speaker (only) for a split second to a battery and it should produce a sharp click.
A typical failure point is one wire of the tether losing solder connection on the engine side of it.
I moved this topic to the appropriate category. This is not about a traditional toy train rather specifically is talking about an MTH PS2 locomotive.
@Engineer-Joe, not real good at electrical issues, but what should the ohm's be reading when checking the speaker only? I did touch the contacts on the speaker and I got no reading at all. I will try the battery test today to see if it makes that pop sound....I'm assuming I can just use a 9volt battery?
The reading with the speaker disconnected, right at the speaker terminals, should be something between like 8 to 16 ohms. They don't always give a reading like their stamped. If you got nothing, try the battery. If that does nothing, the speaker failed open, & it needs to be replaced.
Any battery like a 9 volt, C, D, AA, or AAA for examples. I usually use an AA battery. Don't connect it, just tap it quickly to produce a click.
if your speaker reads open you need a new 8 or 16 ohm speaker probably has a 50 MM speaker inside tender ! mth sell them or asc techs also have them ! typically they used a 16 ohm in the ps 2 5 volt boards ! item number is probably 20-3048-1 or similar

These Visaton 16 ohm 2" Speakers work well for 5V boards. Cheaper than the ones that MTH sells, and IMO a better quality speaker as well.

Thank you all for the help-it was the speaker that was bad. I had a spare one from MTH that I picked up at York and connected it and all works great now.
john your websight to mouser did not work or bring up websight had to bring up mouser and then type in visaton and 16 ohm sepaker for it to come up. kept loading and never came online ?
