LOW VOLUME - LEGACY SD70ACe

Yes return to Lionel for it to be fixed. I had the same issue but decided to return it to the store.

bgraham34 - I am the guy whom freighttrain purchased the SD70 from. The thing is, when I shipped it, the sound volume was great - in fact, it was so loud that I often had to turn the volume knob down a bit.

Before I shipped it, I made sure that it worked great - and the sound was normal.

I would think, that if the sound chip came loose, then there would be NO sound, or static and sound combined. But "low sound" sounds like a setting somewhere?

Perhaps a "reset" of the engine would solve this issue?

I thought the same thing but had no luck at all. I even had a local Lionel tech look at it before i returned it and he said Lionel needs to look at it.

Your problem is the volume pot. I have two of those locomotives and had the same situation.

Hi Marty,
Do you mean that I need to replace the volume pot? I thought I read something about adding to or sodering the wiring around the pot or speakers?

You can jump the wiper on the pot (center lug) to the high volume lug. Jump each outside lug and when you get high volume you are there. If you hit the low volume first with the jumper, no problem. The only thing you give up is that now your locomotive will run with full volume. Not the worst thing. You have now taken the questionable volume pot out of the mix.

Volume pots on both Lionel and MTH locomotives can be bypassed with this method.

If you do this bypass of the pot does the Legacy system volume control still work?

The volume will be set at full by doing this. You are actually connecting pins 16 and 18 on the Legacy Railsounds Audio board by doing this. To have everything working properly so you can adjust the sound replace the pot. The volume pot is very cheap and very easy to replace. I just had to replace one on my Texas Special today.

FYI the same can also be done with an MTH volume pot. Both Lionel and MTH use a 10K volume pot. The MTH pot is larger in size.

Yes but the soft volume adjust on the Legacy remote will still function, eh? I thought that was the question.

Should Chuck.

Yes is the answer. I had one apart on the bench and just tried it. All you're doing is "turning" the volume up full, the software controls still work the same.

If I remember correctly though, you won't be able to turn down the horn, whistle, or bell.
