This past Saturday, Richard Clark asked me to video tape a demonstration of why replacing a large gauge wire makes almost no difference in the voltage being supplied by the alternator.
The car used in this video is Jim Anson's.

thanks for the very detailed video and i see where your theory is true in some ways but i see where it did make a difference on the car and that is all that matters. my biggest thing was i now have more stable voltage and also when i run my assessories it doesnt drop as much as it did before. i too seen a difference in 2 tenths of a volt gain. 13.9 to 14.1 as you did too. not saying it makes a difference but i also changes to a heavy negative too. my end to this thread would have to be that all cars will not benefit from this as all cars are different. i also cant blame it on poor wiring or cluttered engine bay as you can see it is clean and neat. thanks
