I purchased a E-Z Digital Command Control System (BAC44902) this year in May.
I have two Bachmann DCC locomotives that I use. Since I purchased this, occasionally when the speed control was turned all the way off, the locomotives would continue to move at a slow speed. Now this is happening almost all the time. This happens with both locomotives, so I don't think it's the engines. I feel it must be something in the controller.
Has anyone experienced this problem? Is there something I am doing wrong or is this a defect?
I'm glad to see someone is having the same problem as I'm having. I asked this question sometime back and never did get an answer. They just referred me to the manual part about programing locomotives. That didn.t do the trick. I'll follow your posting to see if you get any help. Meanwhile I'll let you know if I fix the problem.
Gentlemen please realize that DCC engines are never fully shut off with the throttles turned to Zero . If you require the engines to be fully off, move them to an area that can be electrically isolated and turn off the power to that area. The same problem came about with real steam locomotives in round houses , their fires were banked overnight but sometimes they ended up in the turntable pits or going thru the walls . John 2.
it sounds like the speed control circuit is defective. have you contacted the service department about this?
a simple workaround to this would be to reprogram the cv2 start voltage to a higher value. unfortunately, you cannot program this with ez command. you will need to find a friend, club, or hobby shop with a full featured dcc system who is willing to make these changes for you.
I have run into this problem and it has been dirty wheels that has been causing it,guess the engine doesn't get a good signal. Clean the wheels off with some alcohol,problem solved. What I have noticed is that the the 2 F units I have are the ones with sound and original pc boards in them, are the ones that it happens to. The ones that I replaced the boards in,to get rid of the hum, doesn't happen to them.
In my case, after talking to the service dept. at Bachmann, I filled out a service request and sent the controller back to them. It couldn't be fixed. For $45 they sent me a new controller. It works great.
