Battery to frame ground

Donkeypuncher · Post by **Donkeypuncher** » Fri Aug 08, 2008 3:57 pm

While upgrading the ground wires I noticed the battery to frame ground only bolts to the sheet metal and not the actually frame. Is there a reason for this, or is it just chrysler being lazy? I ended up using the lower mounting point for the fuse box, after removing the paint first of course.

It just makes me wonder why chrysler would do this. If everything uses the frame for a ground, wouldn't it be better to actually ground the battery to the frame and not the wheel well sheet metal?

I also decided to use 0 gauge wire for the 2 battery grounds, can you say overkill?

its a unibody car, the body and frame is basically one piece so in theroy it makes no difference

Metal is metal, the thickness really doesnt matter for grounds in a 12v application like ours. 0ga wire is huge!

I've been told that before, but it didn't work real well for my amps. I ended up using the seat belt bolts since they bolt to the frame.

The stock ground still had paint under the bolt as well. Not good for grounding. The idle is much better now, and the radio static is gone. I couldn't say if it's the bigger wires or better ground location. I should have change the location with the stock wires first just to see.

I was going to use 4 gauge, but I have a 50' spool of 0 gauge monster cable in the garage. I used some extra 8 gauge for the other grounds, 0 gauge seemed way overkill for those.

0g may be overkill, but it sure won't hurt anything .....

Plus, cleaning paint (or relocating) the ground is a VERY good idea.

Makes me want to go try this on my own car.
