How to install a grounding cable kit - DIY style

[vr2turbo]

ohh ya one more thing, I've actually asked a shop owner of car accessories shop and he told me that grounding cable doesn't really give any difference, at least for his perdana v6. He'd advise me not to install thing kind of fancy stuff.

To me, grounding will work for older cars, where the wire resistant have sort off gone up...
For example, some old car will have like signal light problem, or brake lights problem because earth connection not good. Adding earth will solve the problem....something like that....

Haha yea I think I mentioned in one of my post here. My friend's iswara, the clock on the dashboard doesn't show full digit for "minutes". After installing GC, wallah~ he can perform his usual Malaysian time

Guys, i have some question about grounding.. Dose most cars came with grounding from the positive of the battery? Do we need to unplug the wires from positive if we wanna install a new set at negative? Or just leave it there? Some technical mat saleh (ang mo) told me need to clean the copper of the old wires too >_<'

I know nothing about eletricity, but recently i found out a creepy situation at night, everytime i drove thru that same designation road, the car's headlight will dim even with aircond off :afraid:

When I fitted mine, I did not remove the +ve terminal. Grounding is always the -ve terminal, not +ve.
If the terminal are corroded, then cleaning them will be good.

Wah! if got any stories, please contribute to Ghost Stories topic. Anyway, Chinese 7th Ghost month coming (7/Aug) day before Hari Raya.....

Grounding aka negative cable not fitted to positive side it's fitted to the negative pole of the car battery. You clean the negative terminal is to allow a better flow of current. Less resistance due to oxidize surface.

I though there were some grounding cable coming out from the +ve cause it wrapped kinda thick.
Haha thanks for reminding, gonna make haze soon >_< But not so serious la, i think is some electrical thingy, because that street is one of those streets that can't build road lamp no idea why..

Thanks, so we usually just add-on those wires without touching or moving the old wires?

Yup, just additional grounding cables....

To those who have doubt to add or not to add ground cables
1. start engine, on aircon, radio, headlights
2. use a multimeter to check the voltage between battery negative (black) point to
a)engine b)chassis

if reading is
0v (excellent/perfect) - no need add cables
<0.5v (good) - no need also
0.5v ~1v - need to add cables
>1v - must add cables.

hope this helps

If you found that the old earth cable of the car is no really good, you can change them to newer cables. Car wiring will age also with the car. As the cable are subjected to heat, cold, water, oil and grease. It will deteriorate over time. Also the earth point will get rusted or dirty over the years. That's why when you change or tend to add new point please clean the area with some WD40 and sand lightly on the cable lug to remove any oxidize part and spray it with WD40 then clean it again.

Bro. TR,
Older cars ground cable are pretty thick ones. Lately for the newer cars, I see that the cable are thinner, especially the engine to car body one....

Vr2, depends on what car..I saw that the old Corrolla very thin wires

idnawse, pic pls...

 

[idnawse]
