Need help diagnosing a problem

[Alan Anderson]

I posted a long answer in the other thread.

Our problem was from our own making. I pointed out that the SLOW speed of our transmission was geared to go 19 feet per second, and that the max at high speed should only be around 15 feet per second. The build team chose not to make the change. I didn't realize that the problem would manifest in the way it did, but I packed the parts to make the change because I knew it was coming. It was a hard lesson to learn, but one they won't make again. I felt bad for our alliances that had to play with only 2 players, but we were pretty much a brick. We have one more regional where I hope we will do better.

On the other hand, it was interesting to note how much luck can affect your final ranking. We ended up 25 out of 42. I lost track of how many rounds we missed, but it had to be more than 4. It just emphasizes how important that scouting data is. We were close enough to the top 24 to be considered by an uninformed team. Although we were running by that time, I advised the team to decline any selection in the unlikely chance it occurred. We just were not reliable enough.

We have seen defective main (150A) circuit breakers that would open under high vibration, sometimes even popping open/off.

Lightly tapping on the breaker would sometimes replicate the problem.

One more thing to add to the check list.

We did discover something similar to this I believe, we could force a shut off by wiggling one of the connectors, another great catch by our CSA Alan, I have no idea what we would've done without him or people like him, thanks for the advice. Tomorrow we plan on testing all of the connections with a multimeter after some driving, I will post an update on our findings then.

We had a similar problem and it turned out to be a defective power connector to the radio. Check that. It's an easy fix.
