I recently got some of these cables(see picture below) to control an old RCX motor. Some things to note before reading on. I tried both the medium and large motor blocks and played around with power, rotations, seconds, and even just on, but to no avail. If I program the EV3 to make the RCX motor spin counterclockwise, it does so on any setting without any issues. However, if I program the EV3 to spin the motor clockwise, it only spins for about a third of a second before the motor stops. The EV3 brick doesn’t shut down, just the motor. This happens on any setting. Why is this happening and how do I fix it? Is it some kind of over current or under current protection?
Edit: Just tried the unregulated motor block and that didn’t fix it either.
