MTH Protosound 1 Runs with no battery. Won't with battery.

DO a factory reset, but if you can't get pass reset 1 there is ID conflict and board needs to be reset with chip only techs have.  G

Wouldn't hurt to try another battery....What controller are you using?

Did you first try it at any time with an old battery?

Didn't have an old battery. I knew you could use std 9v temp. so that's what I had. Also checked battery to make sure it was good.

Controller is MTH Z750. I'm leary to attempt a reset. As long as it work's leave it alone. Was mostly currious as to how it would work with no battery. I can see it now, attempt rest, or get it to reset and then it won't work at all. It's put up now. Do not have room for a layout anymore. Just some trains under tree or throw some track on floor for grandkids. I've got a diesel sound board, and a std electronic rev board so if it croaks........ it croaks.

 I know you've put things aside for the time being but there's another thread that's very similar which kind of makes sense..

The battery leads may be reversed. ( no  battery no short)
