The Big 3 Are:

1. Negative battery wire to ground - just replace the negative batt. terminal and wire and ground it to the factory location.

2. Engine block to ground - replace the ground wire from the engine block to the chassis with a bigger wire (maybe 4 gauge to 0 gauge).

3. Alternator to batt - add a fused wire from the positive post on you alternator (the one coming from the battery) to the positive terminal on your battery. DO NOT exchange wires just add a extra one. Make sure it fis fused to the capacity that the wire can handle. Use the same size wire all around. If you use 0 gauge wire for one part of the big three use the same for the other two parts.

Note on #2- Some cars have a batt-engine block connection instead of chassis to engine block...

In the first pick we see Alternator to positive on battery. We also see the negative from the battery to the frame. And Negative on battery to Engine block. (Overview)


In the second picture we see a close up of the battery to engine block (engine block/ grounded side)


In the third picture we see a close up of the alternator to positive on battery (alternator side)


In the forth picture we see a overview of the Alternator to positive on the battery. We also see the ground from the battery to the Engine block. (alternator side)


In the Fifth picture we see a different view of the alternator to positive on the battery. We also see the ground from Battery to the Engine block. And the ground from the battery to the frame. (overview)


In the sixth picture we have a overview of The alternator and the wire from the alternator to the positive on the battery. We also see the Ground from the battery to the engine block. and the ground from the battery to the frame. (Alternator side)


In the seventh picture we see the ground from the battery to the frame. (frame side)



A special thanks goes out to Thieves for the wonderful pictures.

in case you can't tell, it's that shiny thing in between and at the bottom of all those hoses. go frame or go home.

Think i got it now. More pics coming soon.

what if you don't have a frame?

well then chassis is the only option you're going to have.

I was being a smart ass again...

"Make sure it fused the same size as your factory fuse."


...no. It should be fused to the capacity of the wire you're using or a little less. NOT the same as the factory fuse. That is if you even fuse it. There is lots of debate over it and to me it is not necessary. If you do it right then you shouldn't worry.

Thanks. I took care of it.

Good stuff.

did you see the post on the CA forum? this dude kept ref'ing his photos, that was the ugliest, most unkept engine bay I've ever seen. A very poor example of teh big3z. but yeah, the fuse should match the rating of the wirez. good fix here. I'm proud to be helpful lol....

we need more help for other topics still...

Like what Sir Whorederator?

more pictures and everything to help everyone see how to do installs
