MTH SD60 NO SOUND

Thoughts?   Turn the volume pot up a down a few time and a feature reset.

Menu/Advanced/ Reset engine/ Feature reset. 

Turn Doppler on and off again.

Using the new battery (trash the old one), do a Factory Reset:

Menu/Advanced/Reset Engine/Factory Reset

This will also delete the engine from the DCS Remote. Then, re-add the engine

Inspect the speaker  for flaking.  Can be bad, was known issue for some of those star speakers.  Replacement is BF-33.

Other issue is the audio amp.  I have replaced a few on the SD-60/70 engines.

How are sounds in conventional?  G

I have tried all the above suggestions and still no sound. The speaker looks to be in ok shape. Any ideas on what it runs to replace the sound on one of these engines?

Did you trash the old battery before doing the Factory Reset?

A feature should over ride the  following but who knows. Go to

Menu/sound/ make sure all the choices are  set high. Scroll to the percent you want and press the thumb wheel to lock it in.  Is the #4 hard key on the remote set to "on".

I think that I did do a reset on the old battery before I received the new one and put it in. T\I checked the old battery with the multimeter after the first reset and the battery showed 8.7volts. Next day I received the new battery and charged it up to 9.51, replaced with the new battery and then tried all that was suggested today.

I pushed the volume on bell horn and engine sounds o 100 percent and the engine sounds key is on.

I pushed the volume on bell horn and engine sounds o 100 percent and the engine sounds key is on.

So, is everything now working, or not?

Still no sound at all, everything else is working fine, I switched over to conventional and still no sound

OK, got it. It sounds like either the speaker or the audio amp is shot.

Since as GGG correctly notes, the speakers on the older 5 volt PS2 engines are prone to fail, I'd check that first.

If you can disconnect the speaker from the PS2 board, you can connect a meter across the speaker terminals to test continuity. If there's no continuity, replace the speaker. A replacement is about $10 plus shipping from MTH, and the replacement speakers are much improved over the original ones.

If there is continuity, the issue is most likely either a disconnected wire between the speaker and the PS2 board, or the audio amp is blown. If its the audio amp, (George) GGG can fix it for you.

I unplugged the 2 speaker wire connector and checked continunity between the ylw and wht wires to the speaker and I got a reading of 150 on the continunity meter setting. I checked the loco again about 5 minutes ago and when pressing startup, the lights came on and you could hear a faint clicking and crackling noise thru the speaker but no definite sounds so it sounds like the sound is out

I believe 150 ohms across the speaker terminals indicates a speaker bad internally; it's been many years since I had occasion to put an ohmmeter on one.  Do double check the soldered connections on the wires.

I just checked the actual terminals on the speaker and there seems to be a problem. Sometime I get a reading and then nothing. It comes and goes with the meter probes on the actual speaker terminals. Sometime touching the terminals you can hear a faint rasp from the speaker but no reading on the meter, then again it will show a reading.

Be sure to double check the meter leads and probes for bad connections.  I've had that happen.

Meter leads appear to be ok. Gives me a squeal on continuity setting and gives good readings on voltage for battery and ac... Thinking that it is the speaker

Sounds like another ebay nightmare.  NS UP, you did the correct thing in putting your engine on charge.  I hope you did not give it a try before you put it on charge.  If you did and the battery was low, you cooked the audio amp.  If you did not, the guy who sold it to you tried to run it and he cooked it.`The guys are right about the speaker.  I buy them in big amounts and change the speaker when I put in a new green battery.

A new green battery or BCR should be put in any engine when you first get it if it has age and the dreaded 5 volt board. 

DO NOT CHARGE THE WHITE BATTERY, THEY ARE OLD AND NEED TO BE THROWN AWAY.

If you did and the battery was low, you cooked the audio amp.

Marty, this is the first I heard that a low battery can damage a PS2 board.  CAn this happen with Ps2 3-volt boards also?

I've seen dead charging circuits on the 5V board with a white battery, so it's certainly possible that the battery was the cause.  I have a few 3V boards with dead charging circuits, but I don't really have a connection to the battery at this point for those.

I have ordered a new speaker from MTH and it should be here within the next few days. I will post the results and see if I need additional help...Thanks

I received the new speaker today and installed it put a BCR in and charged 1 minute and she fired up just like a brand new one. Purrs like a kitten. Thanks to all the train Pros for all your help and info. I have switched all 10 locomotives to BCR's. As I was removing the old speaker I checked the ohms for the old and new, the new was 16 and the old 52 , not good.
