Re: Victor Burnouts
Thanks Al, I really appreciate your help with ideas, maybe especially the "straws!" We too are grasping at straws. I'm only leery of straws when implementing potential solutions starts adversely affecting the operation of the robot. I had to fight to keep the Victor's on "brake" this year, because we used coast exclusively the last few years and that change was a natural suspect. Any issues with "brake" that you know of?
From your experience if one FET goes would the others naturally follow from the increased workload?
No miswiring that I'm aware of, all replacements were dropped in and wired the same. Backwards would be more likely than two to one motor which wasn't physically possible.
In the build season before we tightened up our construction practices and student (& engineer) training, metal filings could have gotten into the Victors, so that's what we blamed initally. We haven't uncovered any evidence to that effect and that shouldn't have been the cause on later replacements, but you never know for sure.
It's really a concern of course for next year when we won't want a repeat of the issue. I'll get together with the elec. students and other engineers to see if we can add to your straws, and get any stories of static discharge while handling any of the equipment.
