I think we checked the PWM cables and they all seem fine.

Looking at the Jaguar manual "Getting Started", it appears you are correct that the Jaguars will flash fast red/green when the motor is not going full speed and only solid when going full power.

So that explains that part, but it doesn't explain why our robot would cease working when we're driving it. Naturally not knowing anything about the Jaguars, flashing lights seemed bad.

Hm..
