It looks like the problem was the PWM cables not being pushed in far enough. I took the Spike to work and tested it using a DC supply. I was able to get it to work with input voltages much lower (1 V) than what the specifications say is required (3 V).

I don't think that the socket for the PWM cables were worn out since these were brand new. This team has also never used Spikes in their robots before.

Thanks for the tips.
