ok, I finally got to trying some of the stuff you recommended. I recharged the
batteries and tried downloading the firmware. It can run the whole program
without the motors being plugged in. It can even run the program with all motors
plugged in but not connected to any mechanism. However, when I try to run the
program with all 3 motors connected and in place, the RCX goes off and the
motors keep going.
I tried "stopping" one or even 2 of the motors connected to the RCX but
disconnected from the mechanism and it worked. I'm still really confused. What
kind of load can the mechanism excert so that the RCX goes off that I can't?
