Added noise with lights on

[wjstix]

IMHO both generator whine and brake 'squeal' are best if kept at a fairly low volume.

I looked it up, and it's CV 133!

Try a value in it and hear the difference. Start with a low number (maybe 30...), and adjust accordingly.

Good luck.

What you describe is the steam driven electric generator!

As a (real) steamer have no other way of making electricity for the lights, that sound is inevitable......

If you look around on youtube, you will find several examples of the sound!

I can agree that it is a very irritating sound if kept at factory levels though......

If you look in the manual you'll see which CV to change to reduce the volume of it!

I have a Bachmann 4-8-4 Northern and recently replaced the Bachmann decoder with a SoundTraxx Tsunami "heavy steam". It improved the overall operation and the sound was greatly improved. But I notice when I put the headlight on (function "o"), an additional noise starts up. I can only describe it as a kind of a hum or "generator" noise that is very noticeable when the engine is sitting still. When I turn "off" the lights, the noise stops and just the other normal "sounds" of the steam engine are heard. Before I contact SoundTraxx, does anyone know what might cause this? It does not seem to affect how the locomotive runs and it does not cancel out the other steam sounds. JRP
