Fuses..

[I like FI 10+ year member]

If you have a ho alt., does a inline fuse restrict current flow?

The fact that you have a HO alt is irrelevant to the amount of current that will pass through a fuse....

(that is all voltages being the same)

Although your question probably is if I install a inline fuse will it make my investment in my HO alt worthless, which it will cause some voltage drop, but not much

First off, anything and everything, including wire as big as your head, to some extent does add resistance. That said, a good ANL fuse will add an immeasurable amount of resistance to that connection.

It will but as loopkiller said it will be almost unmeasurable. it depends on the size of the wire and the alt

but a fuse doesnt blow with high voltage. it blows on amperage //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

WRONG!

Fuses are rated at a certain voltage for a certain amperage.

They basically blow at a wattage //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif, but in all reality they blow at a certain temperature that is reached from a certain amount of power passing through it, which is as we all know a function of both current and voltage

what if it's high voltage, low amperage though?

anyway i was just fckin w/ dude //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

It blows at temp, caused by power, so if you have a voltage spike with a amperage valley then it wont blow, but........ that is soemthing that would very rarely happen

well, given a stock 130a alt and a 1/0 big 3 (alt to battery fused at 250-300a)...(i'm assuming we're talking big 3)

if the regulator shat itself, and the voltage spiked to 18v... would the alt's amperage output fall due to the increased voltage? or would they both climb until the fuse blew? i have no idea...

what about this guy? :
