Re: Problems with victor blowing
 

We agreed, the reason the circuit was reassembled is we were trying to reconstruct the problem in the lab(rather than when driving). We removed all of our drive electronics and then tested them one thing at a time. We checked for shorts to ground as well as abnormal resistances in motors, and victors. We then added our components together until the whole control system was rebuilt. We are hoping the issue was just with the victors (as Pat said we are contacting IFI). We will update if we find anything else.

I agree with Al Skierkiewicz, if there is a problem it should be addressed replacing the victor would be a good first start. If the problem occurs then the problem is with the circuit. One possibility could be a short in the Victor do to metal shavings. As a habit I use a can of air over the victors every time I drill or cut a piece of the robot when the board is mounted. That could have happened and yes I'm sorry I was confused between the spike and victor. Last night was a long night at the Robot Factory

Sorry I didn't get back to you sooner, we were building a robot :)

I just think that it's helpful to take a few pictures of the wiring/electronics board so we can "look over your shoulder". It is very difficult to diagnose someone else's problems with only a short description of the situation. A picture is worth a thousand words...it may reassure us that you do indeed have everything wired up properly, or we may notice something that you didn't.

Sounds like you may have fixed the problem, even if you don't know what was wrong...I hope it was just some simple thing that you overlooked the first time.

Well it seems that it was a bad CIM motor. It happened once more a week ago. We changed out the motor and it has been fine since then. Most likely a short that occured only in certain positions.
