Posted November 27, 200519 yr Anyone around Dayton OH know how to change the Big 3 on a car? I do not see how to do it, but maybe someone who knows what they are doing could help me. PM me if you can! There is a Fuse box right off the Positive Terminal that throws me off right away. Then the wire to the Alternator seems to be wired under a plastic cover around the engine. I assume if I do the big 3, all that gets removed from the car?Here are two pics of the Fuse box I am speaking of...http://i20.photobucket.com/albums/b...4/Battery01.jpghttp://i20.photobucket.com/albums/b...4/Battery02.jpgAnd here is a Pic of the Alternator, where it apears the power wire goes up inton that hard plastic cover that then wraps around the engine.http://i20.photobucket.com/albums/b...4/Battery03.jpgIs it normal for you all to have to tear the engine apart to change the big 3? All my wires apear to be wrapped in black plastic which is connected to other wires along the way. Like from the Battery terminal you see with the Fuse box, the wire goes straight down then "Y"s off and another wire connects to it, as it gets lost under the engine.
November 27, 200519 yr Author Oops read the Big 3 Post at the top of the page. Now its much clearer, except #2. Where do I look for the Engine Block Ground? And should I use 4 awg or 0 awg? I am using 0 awg from the Battery to the amps.Lastly, A fuse must go between the Alternator and the Positive post of the Battery correct? How do I know what size fuse to get? Thanks!
November 27, 200519 yr I never used a fuse, i didnt feel like spending the extra $30.Engine to chassis, should be a wire going from the block to the frame.Check underneath the car, its probably hidden somewhereI would reccomend anything over 2ga(larger capacity).

I do not mind spending the extra $30 if it means it does something to save my future trouble. And under the car huh?? Whats that wire used for? I mean why does an engine block need a ground wire? I will probably use matching 0 awg for the fun of it. I have 17 Feet of Blue 0 Awg comming. May not need all of it, and could use some to do this project.
November 27, 200519 yr Author Probably for the spark plugs.<{POST_SNAPBACK}>Ahh that sounds like a logical answer lol
November 27, 200519 yr 2 or 1/0 gauge isn't really necessary though would be great. 4 gauge will work fine since the distance between the block/battery is really short; i used 4 gauge in mine. It was a pita to install 4 gauge on the factory ground spot in mine(which was less than a foot from the battery, i just sanded it down)
November 28, 200519 yr Author Could the Engine Ground Stock wire be as small as an 8 awg wire or less? There is one wire I can easily see on the side of the engine, comming out of some black wrap running with other wires, that connects to a bolt on the side front fender of the car. This is a ground for something, just do not know if its the right one or not.
