Thanks.I appreciate the info.

I am new here,but here goes.I have 6 engines programmed on my EZ Command controller.It has been approx. 8 months since i have done anything with the set.Now i have cleaned and re-started,i can only get two of the 6 to work properly.Two of the engines will run on address 3,they just run backwards to the direction arrows.Two are working great and two i havent tried yet.Any suggestions on how to fix the two that are running backwards?The same two wont take a re-program either.I have tried that several times and they act like they are not receiveing the instructions.They respond to speed knob but only on address 3,and then,as i said,they run oppasite to the direction arrows.Any help or suggestions will be helpful.Thanks,Charlie
