Re: Jaguar Red Blinking Light

Looking up on Luminary Micro's website, a slow blinking Red light means a "Fault condition". I'm not exactly sure what this refers to.

What should we look out for to get the Jaguar working again?
There are 4 things that can cause a fault condition:
Power supply under-voltage
Over temperature
Over current
Limit switch activated in the current direction of motion

We had one die on us was well. We checked what we could and eliminated all three causes except 'Over Temp.' It does not make sense for a controller to be "hot" when it hasn't been used in 24 hours. We think there is some sort of malfunction in the temp sensor, however, we do not have the resources nor the expertise to troubleshoot the problem further.

If you come to a FRC event to see a robot competition, you are missing the point.
