Thread: Positive Battery Post completely black - car not starting

The whole point of the big three is to along get rid of the factory cables the grounds can stay but all you need is to run a your new wires from The battery to fuse box then from alternator to fuse box disconnect the originals.

When I helped a friend do his we completely removed factory grounds and wiring. Really if u upgraded all the wires to a much heavier gauge u should remove the stock or at least disconnect it

Take a pic so we can tell you accurately but yes electrical tape

Also explain what u mean by extremely tied up with other stuff. Have u had the battery tested to make sure its fine. And take a pic of said black stuff on it so we can see

i removed all the the facotry wiring that i upgraded except the alternator one, i'll try to do that one tomorrow morning have to study for finals. by tied up i ment it the wires were in a plastic tubbing and within that they were taped together with electrical tape, it doesn't matter anymore since i removed them. um during the winter i had the battery checked at autozone and they said everything was fine, checked my alternator and other stuff as well. I'll upload some pictures i took this morning.

I bought some terminal battery post cleaning kit cleaned the crap out of both posts and replaced a janky factory terminal, i took the car for a small ride to see how it was and its voltage on the DIC was 14.4-8, after about 10 minutes of driving it went down to 13.1-2...im afriad its going to do it again. ill post up the pictures i took in a second

I had already sanded most of it off from the sides when i remembered to take pictures but you can see on the top of this picture there are black blotches, before i had sanded them down the entire post was that color, it actually looked like it was made out of the black plastic casing.

Here it is from the side, you can tell the difference on the bottom of the post where i didn't sand it down very well.


and this is just a top view of the negative post

The most important aspect of "big 3" is to replace the ground wire for the purpose of greater potential. Why? Because smaller asian designed vehicles don't handle extra loads very well since the balance between efficiency and cost of parts was done so well. That's really where a lot of this began. It's also due in part to individuals needing to make repairs to their vehicle. Consequently, not realizing their "big 3" upgrade fixed issues of corrosion, loose connections, etc....people just blame "factory wiring" and now everybody think it's a huge must.

THE MOST IMPORTANT PART OF ADDING ELECTRONICS IS ESTABLISHING A GOOD SOLID GROUND!!! Most people don't...another reason why "big 3" is such a big hit.

Common characteristics of a good ground...
