I just had my new 200 amp alternator installed (97 Ford Explorer) at a local shop, but they said the upgraded 4 gauge cable was not necessary. Were they lying, and if so, how much of a difference would it make?
Thanks
Evan

Lemme ask you this - what size wire is required to carry 200 amps? Then you need to have a wire AT LEAST that big. If you don't, you do run the risk of overheating your primary wire, and causing a fire, performance be damned! DO NOT SKIP THIS STEP... upgrade the wire. A #2 is rated for 225A, so this is the smallest I would go.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

2 guage is kinda hard to find tho, 0 guage is more common, and will have a higher power handleing. ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.
