CAN/Jag Blowouts

[Superllama12]

At Regionals this year, we had some major trouble with CAN. One Jag, which was conveniently located under the lift (which was shedding metal shavings) blew out repeatedly. This was probably due to shorting, although we are rather reluctant to take it apart. Do you think that it was due to shorting, or could it be other things? Also, afterwards, we switched out the Jag, but we were getting ground state errors in the BDC-Comm, anyone know what that could be about?

What do you mean by "blew out repeatedly"?

My definition of "blew out" could only happen to a particular device once.

i am having the same problem except we are just blowing alot of them at random wat i believe is the problem is the motor surges and rederects massive amps back into the jaguar

Perhaps you are referring to a fault condition.

Brandon, when your Jaguar "blows out", do you smell anything? Did it smell like burnt plastic and electronics, or did the Jaguar just stop working temporarily?

As to your "ground state errors", I'm clueless as to what that could mean. The only "errors" I know of are faults. If that's again what you mean, then there's five possibilities: limit switch pressed, over current fault, low voltage fault, over temperature fault, and gate fault.
I know nothing of ground faults in our system.
