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?)?

AGU or anl 60-100amps should be fine

so... you didnt have a fuse near the battery on the wire that goes to the amp?

userlain · 10-12-2004, 07:02 PM

amp? you mean my audio amp, right?

yes my amp wire has a fuse in it

i guess my real question is: qhere is the positive terminal on the alt on a gen2 camry, and how do i rig up a fuse to the 4awg wire im going ot use?

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

so in the case of some elecritcal malfunction, my battery doesn't blow up.

i hear its pretty messy...

...and the debate begins, you need an inline fuse holder for 4 awg, try knukonceptz.com

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?

no

your battery will be fine

***Hamsterman*** · 01-05-2005, 03:49 AM

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.

userlain · 01-05-2005, 03:41 PM

Ok where is the pos terminal on the alternator? I have looked all over and can't find it

^ Its on the top of the alternator, underneath a grey plastic cover.
