Re: TalonSRX Fried?

It would certainly be unsafe to assume anything else.

While I'm not familiar with the specific internals of the Talon, putting a dead short on the output of a power amplifier is a death sentence for the amplifier unless there's specific protection designed in to do an immediate cutoff. Snap action breakers are specifically designed not to cutoff immediately, otherwise we'd trip them with the current spike as a DC motor is started up. Those breakers can do a fair job of protecting wires in which heat is generated over a long run, but not the amplifier electronics where power is switched in a small package. Even at that, we have fried several feet of supply-side wire when we shorted motor controller inputs.
