TT Scale. The Ideal Scale.

Hey gang, after installing an ESU decoder I now have a locomotive with very loud motor noise when previously there was none (pre decoder). It sounds like a non chipped motor on dcc track. Any idea what the deal is and a possible solution?

besides the noise,is the loco running properly. if not i would recheck the wireing. if thats not the problem make sure nothing is rubbing inside. outside of that maybe a bad chip.

Some sites have suggested that changes to CV 9 can help with this.

@ jmass The noise is definately electrical buzzing as opposed to mechanical and the loco runs perfectly fine and all functions work as expected. Also, it's constant with no change in frequency with different motor speeds. It's definately decoder related.

@ CSD I found that page and read it but it's not very helpful in my opinion. I'll play around with the CVs and see if something helps.

What is the model of ESU decoder you are using?

It's a LokSound Micro 52858.

Hum. The only things I can recommend are adjusting CV9 and insuring that the decoder connections are isolated and not shorting on the frame or circuit board. Calling ESU may help.

Dang it, the Lenz Compact I have is very limited and will only program CV 1-8. So, this will have to be dealt with when I get some other controller/programmer

Perhaps a visit to your local hobby shop with loco and track in hand.

Uh huh....
