Frisco Ten-wheeler TMCC Frisco Cab #719 6-38043 Trouble

Hard to believe you could feel 20v AC.  I would pull the loco shell and check for bare wires somewhere. Also check track voltage. These are fairly simple to pull apart and put together.

Not sure if that 10 wheeler is equipped with a back up battery or not, my F12’s are.....if you know yours has one, might be worth a peak, see if it shifted, or leaked??....only thing I could think of off the top of my head.........Pat

A battery might help the sound but blinking class lights are an anomaly. You can check sound in the tender by simply uncoupling it from the engine and see if you get sounds on power up. Lack of serial data will make the sound board act as if its in conventional. If so there is a problem in the engine.

Update:  A little while ago, I pulled the 4-6-0 off the track and placed one of my mikes on it to verify the CC is working fine--the mike worked right away.

So, to demonstrate that I really am insane (definition of insane:  repeating the same action expecting a different outcome), I put the ten-wheeler back on and tried again.  Lo! and Behold!  it ran.  Don't ask me why, but I guess insanity has its benefits.

The remaining problem is that it seems to have about three speed steps:  too slow, pretty fast, and rocket.

Nevertheless, I will run the tests suggested above sometime this week and report back.

Thanks for all the support so far!
