need help on mth engine

If you had a weak battery it could have corrupted the sound file Reload the sound file first and make sure the battery is charged

thanks will give it a try when I get home, $oo

MTH locos occasionally surface with a speaker that the magnet degrades over time, when you take the tender shell off, the magnet looks like it has metal filings or crumbles on it, the metal in the magnet loses it's magnetism, and it's ability to reproduce sounds well. I have seen these work fine for a while, then all of a sudden, very weak sounds, such as you describe. If you take the shell off the tender, you can see right away if that is the problem.

Thanks all will check speaker if bad can I get one from anywhere as long as ohms and size same?

Can you tell me how to find out correct speaker?

Thanks to all for your help, $oo

Nice tutorial in that link. Thanks for posting!

If this is PS-2 (5V) with the 8.4 Volt battery the speaker is a 16 ohm speaker. Depending on the model it could be the 5watt speaker.

They are still available from MTH with an improved speaker.

There are charts out there to match model numbers.

If this is a PS-2 (3V) system with the 2.4V AA batteries, the speakers did not have this problem. Not that a speaker can't go bad, but it wasn't the same issue. G

I have that exact locomotive and everything the guys told you is accurate. What Luke stated is very common with the early 5V systems. I have replaced my speaker two years ago. If you go on the MTH site you will notice an upgraded sound file. I would do what Ben stated and put this upgraded sound file in your locomotive with a new green battery or BCR of your choice.

okay speaker has the metal shavings so thats 1 of 2.

the sound file not so much never done it and haven't the wire cables to do it am going to see if I can find a speaker here locally and try it first.

I also have a MTH service center will let him do the sound file if needed that way something goes poof not on me.

it probably is easy but me and electronics are not the best of friends see my other post on dz-2500 troubles.

thanks for all the advice and help as I rarely run this engine as the sounds are awful like this other wise a real nice engine.

Soo Line, measure the diameter of the speaker, in millimeters, can send you one, cost about $8 and USPS shipping. It is probably either a 45 mm or 50mm speaker.

best I can do is with a usa reg measure tape its a tad over 1 15\16" and 3\4" in depth.

the old part # is NR-05009-01 I think the trade name is Star.

16ohm and 5 watts below that says 231 E

does that help? $oo

Sounds (no pun intendeed) like the BF-0000033. G
