Big 3 - Fuse question

[Virindok 10+ year member]

Hello, I currently have all stock wiring/alt/bat. I have a 4 ga wire going to my amplifier from battery. It has a fuse 6 inches from batt and another fuse 6 inches from amp. When I do the Big 3 this weekend.... what is the best way to wire the alt + to batt +?

Should I run 0 gauge from batt to fuse, then from other side of fuse, 4 ga to amp and 0 gauge to alt +? Would this be sufficient? Or should I run the Alt + directly to the Bat +?

Thanks. I did search and couldn't find my exact situation.

alt directly to the battery. no need to fuse it.

i agree with nine ball. no need to fuse the link between the alt and batt.

The fuses are supposed to protect the wire from taking on too much of a current, getting hot and catching on fire. The cause of this is grounding, completing the DC circuit and allowing full current to flow through (or as much as it can pull, always attempting to take more.)

The fuse 6" from the amp is useless. The power source is at the battery. If the wire is grounded, the fuse at the battery will pop and the circuit will be broken... and your amp itself has fuses in it.

As far as alt-to-battery. It's not necessary. But if you want to, put it as close to the alternator peg as possible. Again, the closer to the source, the better.

A lot of misinformation in this thread. A lot of people don't fuse the alt to the battery wire because it is usually short and very direct, so the chance of the wire getting a snag or falling off it's crimps is rare, but it still can happen, which is where a fuse would come in Handy. Mine is fused since the route is to direct. Also you fuse it as close to the battery as possible, and not the alternator.

not all amps have fuses

what fuses?

if you run it direct and out of the way of dangers no fuse is needed. BUT if you do fuse it, use 2 fuses (one at each source of power... batt/alt).

Are you saying what I said was misinformation?

All the ones past '92 do. lulz

Truth. Never thought of the battery one. Good call, Jco.

and you know i know. but i has no fuse on that wire.
