Losslessly is an adverb Dave (from the adjective lossless) borrowed from the audio engineering world. Even so, I suspect I am in a majority that had no trouble understanding how it was used in that sentence. But to keep this professional, the "Why do you disagree" question is probably best left unaddressed.

In anybody's world, the length of a battery cable is determined by the distance between the two points it connects. We're talking gauge (diameter) here. The gauge selected is electrically dictated by the composition of the wire, the diameter of the cable, and the length of the run. No one's arguing that "larger" cable can't handle more amperage than a "smaller" cable. So sticking to diameter, Chris merely tried to explained to you WHY gauge must increase in proportion to load and length. Heat loss. BE&E 101.

Let's assume for a second that you've never heard of a fuse. It's typically a piece of intentionally undersized wire that is placed in series with an electrical circuit for the express purpose of self-sacrifice in the event of an amperage overload. What blows a fuse? Heat. The diameter of the fuse wire is insufficient to support any amperage that could otherwise be sufficient to damage the equipment it's been inserted to protect.

Geeze, greg, what obscure inane dictionary are using to quote the definition of "losslessly"?. This post just keeps getting stupider and stupider. I know what a fuse does in a circuit, since I used to be an electrician and I wired electroplating machines that had many circuits that had to be individually fused. I had to calculate the total amperage draw in order to determine the circuit breaker size and the size of the cable leading to the machine from the main circuit breaker.
Take your assumptions and do a little fact gathering. The connection between a tractor battery and the starter is not fused. If the cable is undersized the cable will overheat and possibly melt if the amperage draw is greater than the cable can handle.
Get a life, old man, instead of trying to impress other members with your great knowledge of everything to do with tractors.:)

The larger starter cables can handle more amperage. Not a matter of waste, it's amperage.
This is where you went wrong. It has been explained to you. Concentrate on that. You know enuf to figure it out. I hope.
