I'm still not sure whether we can use the negative stud in power distribution. Can anyone give a definite answer?

That electrical layout looks very nice you guys. Great job!

Richard,
Looks really cool, nice job! I would eliminate the ground stud and return the negative leads directly to the distro block. You save some weight in #6 and crimp on connectors and lower the series resistance, not to mention a single point failure if the stud hardware loosens.
How do you like the crimper and the Power Poles so far? We add a touch of solder to the connector just to be sure, before assembly. They crimp on the #12 Chalupa leads OK as well, but again a touch of solder just to be sure.

Thanks, Al.

We will probably lose the stud when we compact the layout somewhat -- right now the footprint is still too large. I agree the stud takes up valuable space and is an extra failure point.

Also, I am not sure that the stud is a COTS component. It was in an old (2003? '04?) KoP but I don't think it was custom made for FIRST. Anyway I would need to get a part number and price to show for material cost analysis if we want to use it on the robot.

Richard,
It seems to me that they were available from Terminal Supply that year.

I recall the same. I did find the 2004 Power Distribution Diagram that shows the stud. Didn't find it at www.terminalsupply.com.

But it does seem to be available at Hot Rod Wires.
