I want to upgrade the last of the big three: the positive from the alternator to the positive on the battery. I was readinga thread and it said that I should add a fuse near the battery+ end of the wire.

My question is this: What type of fuse connection thing do i need, and what amp rating should i use(300?)?

amp? you mean my audio amp, right?

why do you need a fuse between the alternator and the battery?? you won't even know that the fuse blows until your battery is dead

I'm upgrading my big 3, got everything I need except a fuse for the alt + to bat +. Didn't really find the answer I was looking for, but close. I'm getting a voltmeter, so I would know if the fuse blew, but is it a waste of money or should I get one, and if I do, using 4 Gauge wire, what would be the best size fuse? I'm thinking an anl 60amp fuse. Has anyone ever done this upgrade without a fuse and had their battery blow? I don't want to run this into the fuse that the old Alternator wire runs to.

Summed up, is it worth the extra money to buy a fuse for the alt + to bat + where I'll be using 4 gauge wire?

all i can say is this...

i had this debate before online and with friends... why even risk it? A fuse and holder will be like $10 or something... fuses never hurt as long as they are the right size and save troubles down the road

i would look in the fuse box near the batt to see what the existing alt fuse is rated at. Match that one for your new wire.

I'm sure you'd be safe without a fuse since there isn't one from the factory. The alternator only makes 80a so there's no need for a fuse larger than that.

edit: how is that grey plastic cover removed? I tried pulling it, twisting it, prying it... Chiltons manual doesn't specify how to remove it.

Funny, I'm sure I saw a 100A fuse marked ALT in the fuse box near my batt. I'll check tomorrow.

Maybe you got the V6 or maybe its because you have the XLE, or maybe the Gen 4s have 100A, but im 99% the Gen3s are all 80A.

Don't know about on your camry, but on a corolla, you kind of pull it away from the alternator and then parallel to the alternator, along the wire.... if that makes sense. Just mess around with it, it shouldn't be that hard to figure it out.
