Had this happen to one of the jags on our practice robot.
Upon turning on the robot, it would flash yellow (per usual) until we enabled the robot and it would then start slowly blinking red.
Opened up the jag and the plastic fan power connector had apparently 'shaken loose' off of the PCB, exposing two headers.
I cut off the connector and soldered the fan wires directly onto the headers. It has been working fine since.
So, make sure you take a peek inside before you throw it onto your pile of dead jaguars.
ugh, i want victors.
