Title: HO S2 won't start on DC
Post by: standerby on February 26, 2024, 10:24:46 AM
Hello, I am new to HO train world because of my son. We bought a almost brand new HO S2 train. It looks perfect. The only issue is it won't start when I put it on the DC track. There is no sound. The light blinks 10 times, stops, then blinks 10 times again. I am wondering if there is reset button? Thanks for your help.

According to Soundtraxx, 10 light blinks means the deocder is getting too much voltage. Get a meter and measure the voltage at the track. Should not exceed 20 volts. There is no reset button. What power pack are you using?

I finally got time to test it out. The light will come on after voltage is over 15V.

What are you using to power your track that you are getting 15+ volts on the rails even with a locomotive on the track? I could see getting that reading if there was nothing on the track, due to meter loading. But having a load online like the locomotive should drop that track voltage down to 12 or less if you're using an HO controller.

It's a Atlas 2j61. The maximum output is 17v. With the train on the track I get 15.37V.

Have you tried reading the voltage with a known working locomotive on the rails? If so, what was the voltage?
