Big 3 Help

i'm lookin' @ a tut for the big 3 in a civic coupe and see this.

Once you remove the main positive harness of the battery, fuse box, abs and starter wire. It will come off as one hunk. I'll put pitures of that up later since the camera died. Take your new wire and measure it all to the length of the harness removed. Then all you have to do is cut, crimp the new terminals onto the 4 gauge wire. Next insert the measured wire with the new crimps onto the new battery terminals. Follow the directions off the new terminals. Most use allen wrenches to tighten. Simple r&r. Repeat for the gorund wire and your done.

Here are pics of the starter wire and ****** ground.

is this part of the big 3?

under the hood, instead of the pos batt goin' to the alt it goes to a fuse box.

thoughts?

 
You will probably want to fuse your + battery to + alternator...so, depending on what they did in the fuse box, it may be correct. The big 3 is:

+ battery to + alternator

- battery to chassis

engine to chassis

 
Got cha..

from what was read in the tut, 1 wire goes from the fuse box to alt, another wire from starter to batt positive and 1 wire from fuse box to batt positive.

seemed weird to me since he didn't upgrade anything to the alt.

Hey brother, I think you answered you're own question //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif! I think you're being confused by the fuse box. Just pretend the fuse box isn't there.

 
+ to + alt,

- to -***** (on the left side of the engine bay under the air filter box)

- to - chassis (should be 3" off the batt)

should need 8 feet or so (that's leaving you with a little slack)

 
Using all the same color wire (blue) can get confusing

Especially when you need a quick battery JUMP or charge (be carful)

You may want to solider the connections as well; the outside elements of weather are tuff on all wire connections (corrosion will build up between the wire and the connector)

There is nothing negative about upgrading the input power feed to the fuse box

Will increase the input current capabilities of the rest of the electrical system
