Ah, yes, that hadn't even crossed my mind before now. I will do that.

Thanks!

Just remember that current flows through both halves of the circuit - both through the red AND the black wires - so with the knowledge that you should be routing the negative ends back to the Power Distribution Block you now cannot prevent the "jump" across the "Screw Connector Block" because you should only put at most 2 #10 wires in each block. Eh, not that it's going to be a major problem anyway.

Re: Team 172 - Electrical Done!

K.,
<R85> Electrical devices must be wired in accordance with Section 8.3 Robot Rules, using
commercially available copper wire for all electrical connections. Aluminum (or other noncopper
material) wire is prohibited. For examples of acceptable circuit designs, please see
the 2007 Robot Power Distribution Diagram.
Please see the revised diagram on the First website.
I am recommending that teams using the jumper, feed the power inputs to the center of the block so that the current divides down both sides of the jumper. This way the current is divided somewhat so that it does not all pass through the entire jumper.

Re: Team 172 - Electrical Done!

I've just finished re-wiring the 40 amp Victors as per the diagram. All four of them are now routed to the terminal block (and subsequently, the wiring looks a wee bit neater too!)

Thanks for all the input, this would have been bad to miss before the competition!
