Re: Please Help. I need some ideas to isolate this problem :
I think I can't help specifically on this but I can keep hitting you with questions in case you miss any check.
I.E. Does the dummy creates a voltage drop or any other kind of error in the line that will cause the first cell not to toggle? My thinking is that if the dummy is shown as a resistor (let's say that this is the issue) , then the first cell in parallel with the dummy will not have enough current to move to toggle 1.
I am not saying this is the issue, it is quite likely it is not, but have you checked it? is it valid ?
