Would doing this with 4 gauge wire be a waste of time?

I am going to be running about 1100-1200 watts total

I used 4g and it seems fine.. I had a crap load of 4g laying around and no 1/0, so 4g had to do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ok I think ill use 4 gauge.

Are the pics broken in the OP for everyone or is it just a problem on mine? They would have been very helpful

is it necessay to fuse between the batt positive and the alternator positive? becaus ei was doing stuff to my car with my grandpa and he has been a mechanic his entire life and stopped me from doing my big three cause i didnt have a fuse and said i might fry my alt?

opinions wanted

no fuse needed. some do, some don't. isn't "required"

 

[hl26 10+ year member]

is there a large risk in not fusing or is it like a once in a couple thousand thing for somthing bad to happen from not fusing?

 

[jco1385 5,000+ posts]

not much risk at all. seems like a fuse would cause resistance between the alt and battery

btw, mine isn't fused and zero problems. and i have a HO alt

 

[hl26 10+ year member]

aight i appreciate th einput im gonna do my big three today!

 

[na_rsx 10+ year member]

Okay, i understand most of this, but what im wondering.. is why you would need a wire between the engine block and chassis....

there is no current between the two right?? so why is it needed...

or am i being an a moron begginer??

There is a wire between the engine block and chassis, you are upgrading all your wires to a bigger ga. so the electrical current has the same flow. Think of it as a water pipe. If you have a 2 in. pipe flowing into a 1 in. pipe, the rate of flow is cut in half. I hope this helps.

Check these sites out...it is a good reference.

the alternator grounds to the block, but the battery grounds to the frame/chassis. There needs to be a strong link between the two
