Would the Big 3 make a difference?

[7ender 10+ year member]

I'm currently running about 900 total watts out of my 02 Accord 4 cylinder, which I think has an 80 amp alternator.

I don't experience any dimming, etc, but was thinking about doing the big 3 just for the hell of it.

Would it be worth doing/will I notice any difference in output? I don't have a voltage meter so I'm not sure what kind of voltage drops i'm getting, but i'm assuming I should be getting some pulling 900 watts out of completely stock electrical.

Should I do it?

It might help, but it definately wont hurt.

Less resistance in your cars electrical loop is always a good thing.

the first time i did it, with 4g, i noticed an improvement in the ability of the electrical system. when i would use higher powered items like the rear defrost or windows i did not have the drop in voltage or power loss i had before.

Doo ihhtt!

Do you think i'd gain anything in output?

You might...can't hurt. It's cheap and pretty easy to do...DO IT! //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

When everyone is talking about big 3, what are you guys referring to? I assume ground wire, alternator, but what else? This is every thing dealing with battery and alternator I guess?

Alternator to Battery Positive (1), Battery Ground to Chassis (2), Engine Block to Chassis (3) = "Big 3" //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

if you buy extra wire, and you will, you can always upgrade all the grounding points under the hood. i replaced every factory grounding (Neg Batt - Block, Rear Block - Frame, Frame - Motor Mount, Neg Batt - Frame, and Block - Batt Tray but i have no idea why they would ground these two together). also did the Pos Batt - Alt.

yeah, i'd like to do it and even though I know it's very cheap compared to many other electrical upgrades, it's still money.

Being in college and being broke, I really don't want to do it if i'm not going to see any noticeable gain. Guess there's only one way to find out

on the F150 forums, they said not to worry about Alt to bat+ because the stock alt can only put out so many amps regardless. They said that if I were to upgrade my alt, then would be a good time to run new wire from alt to bat. So, should I run new wire from my alt to batt on a stoc alt?
