Grounding Kit for 370Z

ZMan8 · 10-10-2013, 11:59 AM

The grounding kit on my 02 civic helped it greatly, but I don't think it would do noticeable things to the Z. On the civic, every time the radiator fan comes on, the head lights dim, the radio/dash lights dim, etc.. Post grounding kit, I don't have these issues. The Z, IMO, is much better wired OEM than the 02 civic.

I'd think that it was more age related. Did it do that new, or just when it was old and tired?

I didn't own it new, but from my research, the stock grounding was very poor so the light dimming would occur from the factory.

EDIT: I will add I made my own 8 gauge grounding kit. cost $20

I agree that adding a grounding kit wouldn't hurt if the circuit design is sound. You are dealing with impedance and capacitance possibilities that could degrade and/or delay signal integrity. Most of the time this happens at the connector or terminal especially if exposed to the elements. Cleaning the contact surfaces would solve the issues if you could actually get to all of them. Since you probably can't then a grounding kit could help get your Z back to stock form.

Most electromechanical systems have a specification for point to point impedance levels (usually in milli-ohms) and this is what should be measured since there are too many variables involved with how this may or may not affect vehicle performance. You never know, someone in the assembly line could have used the wrong type of conductive grease and your car never reached it's stock performance level to begin with.

Yep, the old civics didn't have return wires from a number of components. Adding a grounding kit was like upgrading to what the a has stock.
