Athearn

[grumpy]

I was playing with my Athearn Challenger  when the sound just shut off. I did all the analyzing I could and had it pinpointed to the decoder. I figured that I would check the wiring diagram and see if they gave me a part no. for the decoder. No part no ; no wiring diagram. I went to the instructions which told me that 2 quick touches on no.10 would shut off the sound . I went back to the layout ;started up the loco , hit no.10 twice and lo and behold the sound came on. I  guess while turning on the lights I must have accidentaly hit no.10 twice to turn off the sound. There are some lessons to be learned 1. Read the instructions ; 2. don't make assumptions 3. no.8 is not the only sound control and no.10 does not just turn the lights of and on.
