I am working on a 30-1159-1 Pennsy 2-8-0 Steam Engine. 5 Volt board. First thing I replaced the battery. In DCS control it runs in forward and reverse, start up and shut down work correctly, all sound etc work correctly as well. In conventional start up and shut down work correctly, all sound etc work correctly but it runs only in forward. Once you apply more volts to the throttle engine moves forward. If you press the direction button it stops and then still moves forward. If you back off the throttle all the way and press the direction button once you reapply the throttle it still goes in forward. I know it is a 5 volt board so anything could be happening. What is my next steps.
Thanks
