I was just trying out having 4 motors to power 4 wheels (one per wheel)
and I saw this effect. I had the two motors on the right side both attached
to output A and the two motors on the left side both attached to input C.
But now I am worried that maybe this electricity generation is possibly going
to be bad for the batteries or something. If I hook the motors up one way
I guess it is generating electricity which flows in the same direction as
that from the betteries but if I did it the other way, it would be flowing
the opposite way to that from the batteries.
Is this something to worry about?
Or is there some other bad thing that will come about from hooking up
two motors to one RCX output?

| I parallel two motors frequently with no ill effects. There is no generation taking place. It will use more battery current for the two motors than it would for one, but it is also doing more work. -- Bob Fay rfay@we.mediaone.net The Shop (URL) (...)
