Power Expander Problems

My team is trying to increase our motor speed on our arm with a power expander, but we have run into a problem. The expander doesn’t want to run our arm, and we have tried everything. We don’t know how to fix it, and with a competition only three days away, we need to find out how to fix it.

Team 367C,

Based on the provided information, it will be hard to determine the source of the problem. Can you please elaborate a little bit more on the issue?

For now, I will attach a wiring diagram of the Power Expander. Hopefully it will take care of your problem.
