Grounding useful?

[Carer]

Because then, a change of battery would take you 1hr to remove the wiring, then 5mins to put the new battery in, then another 2hrs to replace all the wiring and re-test all the vehicle electronics.

 

You know how many components there are in the car?

 

 

converge all grounding points to a common point and direct to battery negative. cannot do it this way?

[Carer]

i am also very tempted to do grounding. but first i am very skeptical and i need to convince myself. can anyone help?

I do not disagree with the voltage drop...but it's insignificant.

I will only believe if the grounding wires lead all over the car, that is

1) one cable goes all the way to the rear of the tail light point.

2) one cable goes all the way to the rear suspension point.

3) one cable goes all the way to the rear seat belt point.

4) one cable goes all the way to the roof light point.

5) cables joint up all the metal with gasket in-between, e.g engine and manifold due to the rubber gasket between them, engine and chassie due to the rubber mount breaking the electric path, etc.

Something like those industrial cable tray, when there will be a short piece of wire to join the two cable trays for electrical continuity!

 

The way I look at many grounding cable, it's just like five cables all from the negative of the battery, joint to the engine bay metal parts. I see the radiator, the engine, the car horn, the front grill metal parts, the alternator being linked up with the grounding cables......which in my opinion is Not ideal.

 

Grounding must be all over the car!!

 

You measure the voltage output from your alternator using a meter. +ve and the alternator body.

 

then measure it on your battery terminals. You will notice the difference in voltage,

 

Then with the multimeter, measure resistance across various points of your chassis. You will be able to register a value. This is what is causing the voltage to drop.

 

Purpose of grounding is to use a better conductor (copper) in place of steel. Hence reducing this drop in voltage.

 

As I have mentioned before, grounding points on your chassis is nothing more than places with screw points. The current flows thru the chassis to reach the -ve of your battery or alternator.

bought a ground cable. but can someone recommand me to a ws or freelace for installation?

 

dun go to freelance. better go to a reputable audio shop

You decide if grounding is good for you or not.

 

1. Skoda comes with grounding.

 

2. Electrons from grounding stops a car from rusting

just as grounding the positive terminal from your

battery will cause a car to rust faster.

 

Any cheap copper cable will work, no need to go

for expensive grounding cables.

have u realised y some call ground from their tow hook to the ground ?

[Fuelsaver]

recently got a chance to use a sjy Mit Lancer Ex for a few days - aircon has to be turned to at least 20 deg C to feel comfortable (not cold) when drivin in local weather, day / night.

 

so much difference when compared to my sju CPT w grounding n VS.

 

either is compressor not gd or effect of grounding n VS.
