What is a grounding kit and how does it benefit someone's car

[pfarmer]

Holy Hell, I will give you my NRG kit and you can do the testing with your electro magnetron reader device.

I find it a little odd that while I have done a differential resistance test of my ground points that none have done any on theirs. The fact is that even if you were completely missing a factory ground you would not need a #4 cable to replace it. When doing so using a stack you have just added a possible problem in the future that the factory grounds never had.

For those that don't have a grounding kit take an amp meter that can measure at least 10 amps (fused) and test your stock system with the vehicle running (and loaded by lighting, audio, ect.) between any ground point and the battery negative. Then consider that for grounding between battery and chassis that a #8 can easily handle 35 amps at 20 feet and about 85 amps from battery to engine block.

With your engine running if you find a problem fix the problem. This seems to be the conclusion of most on other forums I have visited.

Keep in mind that electron flow is from the negative side of the battery and returns via the positive side of the battery. How many here who have installed grounding kits using large diameter wiring bother to increase the size of the positive side of the loads to match? I bet you will find that most of the modules you are trying to increase the signal capabilities are running #12 or smaller wiring for their positive side (good for 20 amps continuous).

Furthermore proper grounding technique dictates matching gauge size to load size (and no longer than necessary) for signal purposes. What size cable should be the supply from your negative terminal to the grounding block (or stack) if all the leads leaving the grounding block are #4 gauge by necessity.

If you really need #4 gauge and have 5 cables leaving the grounding block (or stack) then you need about a 4/0 copper cable (minimum) to the grounding block. with 5 #8 cables at 3 foot lengths that cable should be at least a 3/0. Now consider your alternator. Do any of you actually have an 600-700 amp alternator?
