Thread: 07 prix main ground wires, where at??

I want to upgrade my grounds in my car so I can get rid of this annoying ground loop. Where are the main grounds at? Besides the battery to chassis. I heard there are for of them. Detailed description or pictures would be a huge boner for this one, thanks guys!

Most of the noise is coming from the ignition system on the engine. The main ground is on a transmission bolt/stud (15mm) right above the starter. If the noise is clipped at the engine then you don't have to worry about all of the other grounds in the car. You may be able to run some cables right from the battery(-) to the engine block and chassi. Some ferrite noise suppressors on the large grounds may block out some annoying EMI but these are generally for higher frequency. Couple this with some filters on the equipment supplies and you'll be quiet as a church mouse.

Upgrading grounds does not get rid of noise, filters and suppressors do. Remember, a car is a giant floating ground system, unless you want to drag a cable on the ground will you're driving.

I hope this helps.

Will I have ten feet of zero gauge wire left so I think im just going to find all the grounds and replace them. Or I could just drag some wires behind me like you say lol
